) A company makes electric motors. The probability an electric motor is defective is 0.01. What is the probability that a sample of 300 electric motors will contain exactly 5 defective motors?

Therefore the probability of getting exactly 5 defective motors is 0.10082.

Step-by-step explanation:

Poisson distribution:

Poisson distribution is a tool that the number of an event is likely to occur within a time period.

μ= mean number of occurrence in interval.

Given that,

The probability a  defective electric motor is  0.01.

Total number of motor is 300.

Mean number= μ=(300×0.01)= 3,

The number of defective motor is 5.

The Poisson  distribution

               =0.10082

Therefore the probability of getting exactly 5 defective motors is 0.10082.
