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?
OA. The random variable is continuous. The possible values are x 20.
OB. The random variable is continuous. The possible values are x = 0, 1, 2,...
OC. The random variable is discrete. The possible values are x20.
OD. The random variable is discrete. 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?
OA. The random variable is discrete. The possible values are t>0.
B. The random variable is discrete. The possible values are t= 1, 2, 3,....
OC. The random variable is continuous. The possible values are t> 0.
OD. The random variable is continuous. The possible values are t=1,2,3,....
