An insurance salesman sells on average 10.4 life insurance policies per week. Find the probability that in a particular week he sells 8 policies. Round your answer to 4 decimal places.

And that would be the solution for this case.

Step-by-step explanation:

Previous concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

Solution to the problem

Let X the random variable that represent the number of life insurance policies that the salesman person sells. We know that

And we want to find this probability:

And we can use the probability mass function and we got:

And that would be the solution for this case.

your answer is -9

step-by-step explanation:

it is 10.6 according to my calculations
