The number of power outages at a nuclear power plant has a Poisson distribution with a mean of 4 outages per year. What is the probability that there will be between 1 and 3 (inclusive of both) power outages in a year?

The probability that there will be between 1 and 3 is 0.4152.

Step-by-step explanation:

Let X denote the number of power outages at a nuclear power plant.

It is provided that X follows a Poisson distribution with a mean of 4 outages per year.

The probability mass function of X is:

Compute the probability that there will be between 1 and 3 as follows:

Thus, the probability that there will be between 1 and 3 is 0.4152.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
