If the probability of failure of one part is 25%, what is the probability that the next two parts out of four are also failures?

Example 3.4

The probability of a failed part is 5%. If 20 parts are made from the same machine, what is the average (expected value) and standard deviation of a failure? What is the probability that the first four part will fail?

Probability of the first four parts failing = ∑(probability of part 1 fail + probability of part 2 fail + part 3 + part 4)
