Customers at a gas station pay with a credit card (a), debit card (b), or cash (c). assume that successive customers make independent choices with p(a) = 0.6, p(b) = 0.2, and p(c) = 0.2. (a) among the next 100 customers, what are the mean and variance of the number who pay with a debit card? mean customers variance customers2 explain your reasoning. because we are interested in whether or not a debit card was used, we can use the binomial distribution. x = the number of customers who use a debit card. because we are interested in whether or not a debit card was used, we can use the binomial distribution. x = the probability that a customer used a debit card. because we are interested in whether or not a debit card was used, we can use the binomial distribution. x = the number of customers at the gas station. (b) answer part (a) for the number among the 100 who don't pay with cash. mean customers variance customers2
