Question

The average number of bridge construction projects that take place at any one time in a certain state is 7.

What is the probability that the company will receive 7 property damage claims on a randomly selected day? Answer choices are rounded to the hundredths place.

a.)0.44

b.)0.34

c.) 0.14

d.) 0.59

Answer 1

Solution:

Given: The average number of bridge construction projects that take place at any one time in a certain state is 7.

X= Number of bridge construction projects that take place at any one time in a certain state follows a Poisson distribution with mean =

Probability mass function of Poisson distribution is:

Find  the probability that the company will receive 7 property damage claims on a randomly selected day

P( X= 7 ) =...........?

Thus correct answer is: c.) 0.14
