QUESTION:

Refer to Exercise 3.142 (c). If the number of phone calls to the fire department, $Y$ , in a day has

a Poisson distribution with mean 5.3, what is the most likely number of phone calls to the fire

department on any day?

ANSWER:

Solution

Step 1 of 1

We have to find the no.of phone calls per day to the fire department

Let Y is the no.of phone calls to the fire department

Here $Y\sim{}Poisson(\lambda{})$
