(a) The number of customers arriving at a bank between noon and 1:00 P.M.

(i) The random variable is continuous. The possible values are x >= 0.

(ii) The random variable is discrete. The possible values are x = 0, 1, 2,...

(iii) The random variable is continuous. The possible values are x = 0, 1, 2,...

(iv) The random variable is discrete. The possible values are x >= 0.

(b) The amount of snowfall

(i) The random variable is continuous. The possible values are s = 0, 1, 2,...

(ii) The random variable is discrete. The possible values are s >= 0.

(iii) The random variable is discrete. The possible values are s = 0, 1, 2,...

(iv) The random variable is continuous. The possible values are s >= 0.

**(a) (ii) The random variable is discrete. The possible values are x = 0, 1, 2,...**

Discrete variables are limited in the values they can take between 9 and ∞

(b) (iv) The random variable is continuous. The possible values are s >= 0. Snowfall can be a decimal and can vary between 0 and ∞
