Question

A shipment of five computers two or that are slightly defective. If a retailer receives three of these computers at random, list the elements of the sample space S using the letter P and N for defective and non-defective computers respectively. To teach sample point assign a value X of the random variable X representing the number of computers purchased by the retailer which are slightly defective.

Solution

The Sample space S is the following

1. 3 non-defective, NNN

2. 2 non-defective and 1 defective, PNN

3. 1 non-defective and 2 defective, PPN

Let X be the random variable representing number of computers purchased being defective

1. NNN, X=0

2. PNN, X=1

3. PPN, X=2
