Which of the following numbers could not possibly be a probability? Justify your answer.
a. 5/6
b. 3.5
c. 0
Suppose thatE is an event. Use probability notation to represent
(a) the probability that event E occurs.
(b) the probability that event Eoccurs is 0.436
Let A and B be events of a sample space.
Part (a) Suppose that A and (not B) are mutually exclusive. Explain why B occurs when A occurs.
Part (b) Suppose that B occurs whenever A occurs Explain why A and (not B) are mutually exclusive.
For each of the following probability histograms of binomial distributions, specify whether the success probability is less than, equal to, or greater than 0.5. Explain your answers.

Oklahoma State Officials. Refer to Table 5.1 on page 196.
(a). List the possible samples without replacement of size 3 that can be obtained from the population of five officials. (Hint: There are 10 possible samples.)
If a simple random sample without replacement of three officials is taken from the five officials, determine the probability that
(b). the governor, attorney general, and treasurer are obtained.
(c). the governor and treasurer are included in the sample.
(d). the governor is included in the sample.
