2x+5=5x-25
Subtract 2x from both sides
Add 25 to both sides
30=3x
Then replace x with 10
2(10)+5 =25
25 times 2 =50
Answer:
The probability that on a randomly selected day the statistics professor will have five messages is 0.1755.
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.
