A batch of 85 machined parts contains 12 that do not conform to customer requirements. Define the random variable, determine the range of possible values and calculate the probabilities for each of the following options.

24 parts are randomly selected with replacement, what is the probability that at least 4 of them are nonconforming?

13 Parts are selected without replacement, what is the probability that exactly 6 of them are nonconforming?

Answer #1

Let the number of parts non-conforming is out of 24.

Then,

The probability that at least 4 of them are nonconforming is

Let the number of parts non-conforming is out of 13.
