Answer:
0.91824 = 91.824% probability that more than 3 students will have their automobiles stolen during the current semester.
Explanation:
We have only the mean, which means that the Poisson distribution is used to solve this question.
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.
Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semester.
This means that

What is the probability that more than 3 students will have their automobiles stolen during the current semester?
This is:

In which

So
Then


0.91824 = 91.824% probability that more than 3 students will have their automobiles stolen during the current semester.
