# Suppose that three microchips in a production run of forty are defective. A sample of five is no be selected to be checked for defects. How many different sample can be chosen? How many sample will contain at least one defective chip? What is the probability that a randomly chosen sample of five contain at least one defective chip?

To determine

(a)

The number of different samples can be chosen.

Explanation

Given information:

Total number of defective productions is 40 and number of chosen products is 5.

Concept used:

From n objects r number of objects can be chosen randomly in (nr) ways.

(nr)=n!(nr)!r!

To determine

(b)

The number of samples will contain at least one defective chip.

To determine

(c)

The probability that a randomly chosen sample of five contains at least one defective chip.
