Problem 41E

A quality control plan calls for randomly selecting three items from the daily production (assumed large) of a certain machine and observing the number of defectives. However, the proportion p of defectives produced by the machine varies from day to day and is assumed to have a uniform distribution on the interval (0, 1). For a randomly chosen day, find the unconditional probability that exactly two defectives are observed in the sample.

For a randomly chosen day, find the unconditional probability that exactly two defectives are observed in the sample.

ANSWER:

Solution:

Step 1 of 2:

A quality control plan cells for randomly selected three item from the daily production of a certain machine and observing the number of defectives.

The probability, p, of defectives have a uniform distribution on the interval (0,1).

We have to find the unconditional probability that exactly two defectives are observed in the sample.
