When calculating probability, there are two rules to consider when determining if two events are independent or dependent and if they are mutually exclusive or not.
The Multiplication Rule
If A and B are two events defined on a sample space, then: P(A AND B) = P(B)P(AB).
This rule may also be written as: P(AB) = $\frac{P(A\text{AND}B)}{P(B)}$
(The probability of A given B equals the probability of A and B divided by the probability of B.)
If A and B are independent, then P(AB) = P(A). Then P(A AND B) = P(AB)P(B) becomes P(A AND B) = P(A)P(B).
The Addition Rule
If A and B are defined on a sample space, then: P(A OR B) = P(A) + P(B)  P(A AND B).
If A and B are mutually exclusive, then P(A AND B) = 0. Then P(A OR B) = P(A) + P(B)  P(A AND B) becomes P(A OR B) = P(A) + P(B).
Klaus is trying to choose where to go on vacation. His two choices are: A = New Zealand and B = Alaska
 Klaus can only afford one vacation. The probability that he chooses A is P(A) = 0.6 and the probability that he chooses B is P(B) = 0.35.
 P(A AND B) = 0 because Klaus can only afford to take one vacation
 Therefore, the probability that he chooses either New Zealand or Alaska is P(A OR B) = P(A) + P(B) = 0.6 + 0.35 = 0.95. Note that the probability that he does not choose to go anywhere on vacation must be 0.05.
Carlos plays college soccer. He makes a goal 65% of the time he shoots. Carlos is going to attempt two goals in a row in the next game. A = the event Carlos is successful on his first attempt. P(A) = 0.65. B = the event Carlos is successful on his second attempt. P(B) = 0.65. Carlos tends to shoot in streaks. The probability that he makes the second goal GIVEN that he made the first goal is 0.90.
a. What is the probability that he makes both goals?
a. The problem is asking you to find P(A AND B) = P(B AND A). Since P(BA) = 0.90: P(B AND A) = P(BA) P(A) = (0.90)(0.65) = 0.585
Carlos makes the first and second goals with probability 0.585.
b. What is the probability that Carlos makes either the first goal or the second goal?
b. The problem is asking you to find P(A OR B).
P(A OR B) = P(A) + P(B)  P(A AND B) = 0.65 + 0.65  0.585 = 0.715
Carlos makes either the first goal or the second goal with probability 0.715.
c. Are A and B independent?
c. No, they are not, because P(B AND A) = 0.585.
P(B)P(A) = (0.65)(0.65) = 0.423
0.423 ≠ 0.585 = P(B AND A)
So, P(B AND A) is not equal to P(B)P(A).
d. Are A and B mutually exclusive?
d. No, they are not because P(A and B) = 0.585.
To be mutually exclusive, P(A AND B) must equal zero.
A community swim team has 150 members. Seventyfive of the members are advanced swimmers. Fortyseven of the members are intermediate swimmers. The remainder are novice swimmers. Forty of the advanced swimmers practice four times a week. Thirty of the intermediate swimmers practice four times a week. Ten of the novice swimmers practice four times a week. Suppose one member of the swim team is chosen randomly.
a. What is the probability that the member is a novice swimmer?
a. $\frac{28}{150}$
b. What is the probability that the member practices four times a week?
b. $\frac{80}{150}$
c. What is the probability that the member is an advanced swimmer and practices four times a week?
c. $\frac{40}{150}$
d. What is the probability that a member is an advanced swimmer and an intermediate swimmer? Are being an advanced swimmer and an intermediate swimmer mutually exclusive? Why or why not?
d. P(advanced AND intermediate) = 0, so these are mutually exclusive events. A swimmer cannot be an advanced swimmer and an intermediate swimmer at the same time.
e. Are being a novice swimmer and practicing four times a week independent events? Why or why not?
e. No, these are not independent events.
P(novice AND practices four times per week) = 0.0667
P(novice)P(practices four times per week) = 0.0996
0.0667 ≠ 0.0996

 Find P(B AND D).
 Find P(B OR D).
 P(B AND D) = P(DB)P(B) = (0.5)(0.4) = 0.20.
 P(B OR D) = P(B) + P(D) − P(B AND D) = 0.40 + 0.30 − 0.20 = 0.50
Studies show that about one woman in seven (approximately 14.3%) who live to be 90 will develop breast cancer. Suppose that of those women who develop breast cancer, a test is negative 2% of the time. Also suppose that in the general population of women, the test for breast cancer is negative about 85% of the time. Let B = woman develops breast cancer and let N = tests negative. Suppose one woman is selected at random.
a. What is the probability that the woman develops breast cancer? What is the probability that woman tests negative?
a. P(B) = 0.143; P(N) = 0.85
b. Given that the woman has breast cancer, what is the probability that she tests negative?
b. P(NB) = 0.02
c. What is the probability that the woman has breast cancer AND tests negative?
c. P(B AND N) = P(B)P(NB) = (0.143)(0.02) = 0.0029
d. What is the probability that the woman has breast cancer or tests negative?
d. P(B OR N) = P(B) + P(N)  P(B AND N) = 0.143 + 0.85  0.0029 = 0.9901
e. Are having breast cancer and testing negative independent events?
e. No. P(N) = 0.85; P(NB) = 0.02. So, P(NB) does not equal P(N).
f. Are having breast cancer and testing negative mutually exclusive?
f. No. P(B AND N) = 0.0029. For B and N to be mutually exclusive, P(B AND N) must be zero.
A school has 200 seniors of whom 140 will be going to college next year. Forty will be going directly to work. The remainder are taking a gap year. Fifty of the seniors going to college play sports.

Let A = student is a senior going to college.
Let B = student plays sports.
P(B) = $\frac{140}{200}$
P(BA) = $\frac{50}{140}$

 P(B′) = 0.60
 P(D AND B) = P(DB)P(B) = 0.20
 P(BD) = $\frac{P\text{(}B\text{AND}D\text{)}}{P\text{(}D\text{)}}$ = $\frac{\left(0.20\right)}{\text{(0}\text{.30)}}$ = 0.66
 P(D AND B′) = P(D)  P(D AND B) = 0.30  0.20 = 0.10
 P(DB′) = P(D AND B′)P(B′) = (P(D)  P(D AND B))(0.60) = (0.10)(0.60) = 0.06

Chapter Review
The multiplication rule and the addition rule are used for computing the probability of A and B, as well as the probability of A or B for two given events A, B defined on the sample space. In sampling with replacement each member of a population is replaced after it is picked, so that member has the possibility of being chosen more than once, and the events are considered to be independent. In sampling without replacement, each member of a population may be chosen only once, and the events are considered to be not independent. The events A and B are mutually exclusive events when they do not have any outcomes in common.
Formula Review
The multiplication rule: P(A AND B) = P(AB)P(B)
The addition rule: P(A OR B) = P(A) + P(B)  P(A AND B)

A special deck of cards has ten cards. Four are green, three are blue, and three are red. When a card is picked, its color of it is recorded. An experiment consists of first picking a card and then tossing a coin.
 List the sample space.
 Let A be the event that a blue card is picked first, followed by landing a head on the coin toss. Find P(A).
 Let B be the event that a red or green is picked, followed by landing a head on the coin toss. Are the events A and B mutually exclusive? Explain your answer in one to three complete sentences, including numerical justification.
 Let C be the event that a red or blue is picked, followed by landing a head on the coin toss. Are the events A and C mutually exclusive? Explain your answer in one to three complete sentences, including numerical justification.
The coin toss is independent of the card picked first.
 {(G,H) (G,T) (B,H) (B,T) (R,H) (R,T)}
 P(A) = P(blue)P(head) = $\left(\frac{3}{10}\right)$$\left(\frac{1}{2}\right)$ = $\frac{3}{20}$
 Yes, A and B are mutually exclusive because they cannot happen at the same time; you cannot pick a card that is both blue and also (red or green). P(A AND B) = 0
 No, A and C are not mutually exclusive because they can occur at the same time. In fact, C includes all of the outcomes of A; if the card chosen is blue it is also (red or blue). P(A AND C) = P(A) = $\frac{3}{20}$

Three professors at George Washington University did an experiment to determine if economists are more selfish than other people. They dropped 64 stamped, addressed envelopes with $10 cash in different classrooms on the George Washington campus. 44% were returned overall. From the economics classes 56% of the envelopes were returned. From the business, psychology, and history classes 31% were returned.
Let: R = money returned; E = economics classes; O = other classes
 Write a probability statement for the overall percent of money returned.
 Write a probability statement for the percent of money returned out of the economics classes.
 Write a probability statement for the percent of money returned out of the other classes.
 Is money being returned independent of the class? Justify your answer numerically and explain it.
 Based upon this study, do you think that economists are more selfish than other people? Explain why or why not. Include numbers to justify your answer.
 P(R) = 0.44
 P(RE) = 0.56
 P(RO) = 0.31
 No, whether the money is returned is not independent of which class the money was placed in. There are several ways to justify this mathematically, but one is that the money placed in economics classes is not returned at the same overall rate; P(RE) ≠ P(R).
 No, this study definitely does not support that notion; in fact, it suggests the opposite. The money placed in the economics classrooms was returned at a higher rate than the money place in all classes collectively; P(RE) > P(R).
The following table of data obtained from www.baseballalmanac.com shows hit information for four players. Suppose that one hit from the table is randomly selected.
Name  Single  Double  Triple  Home Run  Total Hits 
Babe Ruth  1,517  506  136  714  2,873 
Jackie Robinson  1,054  273  54  137  1,518 
Ty Cobb  3,603  174  295  114  4,189

Total  8,471  1,577  583  1,720  12,351 
Are "the hit being made by Hank Aaron" and "the hit being a double" independent events?
 Yes, because P(hit by Hank Aaronhit is a double) = P(hit by Hank Aaron)
 No, because P(hit by Hank Aaronhit is a double) ≠ P(hit is a double)
 No, because P(hit is by Hank Aaronhit is a double) ≠ P(hit by Hank Aaron)
 Yes, because P(hit is by Hank Aaronhit is a double) = P(hit is a double)
United Blood Services is a blood bank that serves more than 500 hospitals in 18 states. According to their website, a person with type O blood and a negative Rh factor (Rh) can donate blood to any person with any bloodtype. Their data show that 43% of people have type O blood and 15% of people have Rh factor; 52% of people have type O or Rh factor.
 Find the probability that a person has both type O blood and the Rh factor.
 Find the probability that a person does NOT have both type O blood and the Rh factor.

P(type O OR Rh) = P(type O) + P(Rh)  P(type O AND Rh)
0.52 = 0.43 + 0.15  P(type O AND Rh); solve to find P(type O AND Rh) = 0.06
6% of people have type O, Rh blood

P(NOT(type O AND Rh)) = 1  P(type O AND Rh) = 1  0.06 = 0.94
94% of people do not have type O, Rh blood

Let D = event that a student takes a distance learning class and E = event that a student is a part time student
 Find P(D AND E).
 Find P(ED).
 Find P(D OR E).
 Using an appropriate test, show whether D and E are independent.
 Using an appropriate test, show whether D and E are mutually exclusive.
