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.customers arriving at a bank between noon and 1:00 p. m.. (b) the amount of snowfallamount of snowfall.

(a)Discrete Variable

(b)Continuous Variable

Step-by-step explanation:

Discrete Variables are variables which can only take on a finite values.

Continuous variable on the other hand can take on an uncountable set of values.

(a) The number of customers arriving at a bank between noon and 1 : 00 p.m is a Discrete Variable. Possible number of customers are 30,56,100,43 etc

(b)The amount of snowfall is a Continuous Variable. Possible values are 0.1 and 15.75 Inches of Snow.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
