Question

A bakery gets an average of 20 phone orders in a 2 hour time period. In order to find the probabiltiy that the bakery will get exactly 2 phone ordersin a 15 minutes period using the poisson distribution, what is the average numer of phone orders per 15 minutes?

Answer 1

The average number of phone orders per 15 minutes is 5.

Step-by-step explanation:

In order to find the average number of phone orders per 15 minutes, we can use the fact that the bakery gets an average of 20 phone orders in a 2-hour time period. Since there are 4 sets of 15 minutes in a 2-hour period, we can divide the average number of phone orders by 4 to get the average number of phone orders per 15 minutes:

Average number of phone orders per 15 minutes = 20 phone orders / 4 sets = 5 phone orders.
