About 7% of men in the United States have some form of red-green color blindness. Suppose we want to simulate randomly selecting 4 U.S. adult males to determine the probability that at least one is red-green color-blind. Which of these are correct assignments of digits for this simulation?

• 0-7 = color-blind, 8-9 = not color-blind

• 1-6 = color-blind, 7-10 = not color-blind

• 01-07 = color-blind, 08-99 & 00 = not color-blind

• 00-10 = color-blind, 11-99 = not color-blind

The probability that a randomly selected student in AP Statistics will do their closer on time is 0.18. What's the probability that out of a group of 6 students, at least one of them will turn their closer on time?

• 0.000034

• 0.82

• 0.304

• 0.696

• 0.18

The probability that a randomly selected student in AP Statistics will do their closer on time is 0.18. What's the probability that out of a group of 6 students, none of them turn their closer in on time?

• 0.000034

• 0.82

• 0.304

• 0.696

• 0.18

Let's pretend that on this test last year students averaged a 6 out of 10 on the multiple choice section with a standard deviation of 2. If Mrs. O was feeling crazy and doubled each MC score then subtracted 1, what would the new mean and standard deviation be?

• mean = 6, sd = 2

• mean = 12, sd = 4

• mean = 11, sd = 3

• mean = 11, sd = 4

• mean = 12, sd = 3

An assignment of probability must obey which of the following?

• The probability of any event must be a number between 0 and 1, inclusive.

• The sum of all the probabilities of all outcomes in the sample space must be exactly 1.

• The probability of an event is the sum of the outcomes in the sample space which make up the event.

• All of these reasons

An event A will occur with probability 0.5. An event B will occur with probability 0.6. The probability that both A and B will occur is 0.1.
The conditional probability of A given B is

• .5

• .3

• .2

• 1/6

If you buy one ticket in the Provincial Lottery, then the probability that you will win a prize is 0.11. If you buy one ticket each month for five months, what is the probability that you will win at least one prize?

• .55

• .50

• .44

• .45

Suppose that A and B are two independent events with P(A) = .2 and P(B) = .4. 
P(A∩B^C) is

• .08

• .12

• .52

• .60
