On average, five customers visit a children's department store each hour. using poisson distribution, calculate the probability of three customers shopping at the store.

The probability is of 0.1404 or 14.04%.

Step-by-step explanation:

The Poisson Distribution formula is given by:

Where:

,

is Euler's constant,

is the number of successes of which we're trying to calculate the probability of occurring.

In this exercise we have that:

.

Replacing in the formula we get:

Therefore the probability of three customers shopping at the store in an hour is of 0.1404 or 14.04%.
