Answer:

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.
In the Poisson distribution, the mean is the same as the variance.
P(X = 0) = 0.09


So

We apply ln to both sides, which is the inverse operation of the exponential.
So


Multiplying by -1

So
