Step-by-step explanation:
Let the random variable <em>X</em> represent the number of e-mail messages per day a statistics professor receives from students.
The random variable is approximated by the Poisson Distribution with parameter <em>λ</em> = 5.
The probability mass function of <em>X</em> is as follows:

Compute the probability that on a randomly selected day she will have five messages as follows:


Thus, the probability that on a randomly selected day the statistics professor will have five messages is 0.1755.

Step-by-step explanation:
What you have to do here is plug in the numbers 2, 3, 4, and 5 in for i in the equation and then add the sums together:
