The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 4.5 per week. Find the probability of the following events.

a. No accidents occur in one week.
b. 5 or more accidents occur in a week.
c. One accident occurs today.

a) 0.01111

b) 0.4679

c) 0.33747

Step-by-step explanation:

We are given the following in the question:

The number of accidents per week can be treated as a Poisson distribution.

Mean number of accidents per week = 4.5

Formula:

a) No accidents occur in one week.

b) 5 or more accidents occur in a week.

c) One accident occurs today.

The mean number of accidents per day is given by

b

step-by-step explanation:

the answer is b.)
