You will have to multiply 80 and the percentage. First you will have to change the percentage to a decimal which in this case it will be 0.39 ( for the first one) so then multiply it so it will be 80x0.39=31.2 and you will do the same with the others just replace the numbers with the one that you are doing hope this helps.

Answer:
0.9975 = 99.75% probability of getting at least 1 call between eight and nine in the morning.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval
The number of calls received by an office on Monday morning between 8:00 AM and 9:00 AM has a mean of 6.
This means that
Calculate the probability of getting at least 1 call between eight and nine in the morning.
Either you get no calls, or you get at least one call. The sum of the probabilities of these events is decimal 1. Mathematically, we have that:
We want . So
In which
Then
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0025 = 0.9975[tex]
0.9975 = 99.75% probability of getting at least 1 call between eight and nine in the morning.
D. 18%
Cuz .18 multiply by 100 is 18
