Question:

Consider the set of integers 1, 2, 3, 4, and 5.
a. One integer is selected at random. What is the probability that it is odd?
b. Two integers are selected at random (one at a time with replacement so that each of the five is available for a second selection). Find the probability that neither is odd; exactly one of them is odd; both are odd.
