A company makes electric motors. The probability an electric motor is defective is 4%. What is the probability that a sample of 60 electric motors will contain exactly 2 defective motor?

Step-by-step explanation:

Given

--- proportion

--- defective motors

--- sample size

Required

Determine the probability that exactly 2 is defective

This follows a Poisson distribution and will be solved using:

Where

u = Expected number of occurrence, and it is calculated as:

So:

becomes

Hence, the probability that exactly 2 out of 60 will be defective is 0.2613

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
