For the next 6 customers to enter the store, (a) find the probability that 1 of them will pay cash, 1 will write personal checks, 1 will use charge cards, and the rest will buy nothing. (b) find the probability that there is at least four will buy nothing. (c) find the probability that at most 2 will either pay cash or use charge cards. (d) find the probability that exact 2 will use charge cards given that exact 3 of them will buy nothing. a standard
