-a discrete random variable

-either a continuous or a discrete random variable, depending on the number of the customers

Answer 1

a discrete random variable

Explanation:

You can only have a natural number of clients entering the store.

For example, 0 clients, 1 client, 2 clients, 100 clients, ...

You cannot have a decimal value, for example, 0.5 clients.

So the correct answer is:

a discrete random variable
