g A life insurance salesman sells on the average 3 life insurance policies per week. Calculate the probability that in a given week he will sell 2 or more policies but less 4 policies.

44.80% probability that in a given week he will sell 2 or more policies but less than 4 policies.

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.

A life insurance salesman sells on the average 3 life insurance policies per week.

This means that

Calculate the probability that in a given week he will sell 2 or more policies but less 4 policies.

In which

44.80% probability that in a given week he will sell 2 or more policies but less than 4 policies.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
