At the Bank of Canada, past data show that 8card holders default at some time in their lives. On one recent day, this bank issued 12 credit cards to new customers. 1. Find the probability that of these 12 customers, eventually (a) at least 3 will not default (b) at most 5 will not default (c) between 3 and 5 (inclusively) will default. 2. Find the expected value and the standard deviation of the number of customers who will not default.
