Giovanny Blankenship · Answer 1

b. a discrete random variable

Step-by-step explanation:

The number of customers that enter a store during a given day is a positive integer. That is, we do not expect fractional values for the random variables since the number of persons visiting the store must be integer rather than fractional. So the distribution of the random variable will be discrete in nature rather than continuous. Among the given options, option B satisfies this requirement.

b) a discrete random variable

Step-by-step explanation:

Reason:

Discrete random variable is a of a finite.

Random variables are considered as discrete random variable when there are finite number of entities.

In this case the number of customers that come in a store are finite/countable and is an example discrete random variable
