Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable. (a) The number of customers arriving at a bank between noon and 1:00 P.M.. (b) The time it takes to fly from City A to City B. (a) Is the number of customers arriving at a bank between noon and 1:00 P.M. discrete or continuous? O A. The random variable is discrete. The possible values are x = 0, 1, 2,... O B. The random variable is continuous. The possible values are x 2 0. O C. The random variable is discrete. The possible values are x 2 0. O D. The random variable is continuous. The possible values are x = 0, 1, 2,. (b) Is the time it takes to fly from City A to City B discrete or continuous? O A. The random variable is discrete. The possible values are t > 0. O B. The random variable is continuous. The possible values are t = 1, 2, 3, .... O C. The random variable is discrete. The possible values are t - 1, 2, 3, .... O D. The random variable is continuous. The possible values are t> 0
