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.

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
