Suppose the probability that a person says he or she was at the Woodstock Festival and Concert is 0.20. An experiment consists of randomly selecting people in Green Bay and asking them whether they were at Woodstock. The experiment stops as soon as one person says he or she was there. The random variable X is the number of people stopped and questioned (until one person says he or she was there). Let Y and N stand for a Yes and No response, respectively.
a. List the first several outcomes in the sample space.
b. Find the probability of each outcome in part (a).
c. Find the value of the random variable associated with each outcome in (a).
d. Find a formula for the probability distribution of X.
