It has been estimated that only about 25% of California residents have adequate earthquake supplies. Suppose we are interested in the number of California residents we must survey until we find a resident who does not have adequate earthquake supplies. A) Give the distribution of X. B) What is the probability that we must survey just 1 or 2 residents until we find a California resident who does not have adequate earthquake supplies? C) What is the probability that we must survey at least 3 California residents until we find a California resident who does not have adequate earthquake supplies?
