Of 100 electrical relays produced at a factory, on average 1 is defective. in a production run of 500 electrical relays, what is the probability that the number of defective relays is at most 2?

Answers

The probability that the number of defective relays is at most 2 is 0.1246.

How to calculate the probability?

It should be noted that of 100 electrical relays produced at a factory, on average 1 is defective.Thisimplies that the probability of a defective is 0.01.

Therefore, the probability that the number of defective relays is at most 2 will be:

= e^-5 × (5^0/0! + 5/1! + 52/2!).

= 0.1246

Therefore, the probability that the number of defective relays is at most 2 is 0.1246.

probabilitythat the number of defective relays is at most 2 is 0.1246.## How to calculate the probability?
