Question 1189853: Do what is indicated.
2. Two balls are drawn in succession without replacement from an urn containing 5 red calls and 6 blue balls. Let Z be the random variable representing the number of blue balls. Find the values of the random variable Z.
2. A shipment of five computers contains that are slightly defective If a retailer receives three of these computers at random, list the elements of the sample space S using the letters D and N for defective and non-defective computers, respectively To each sample point, assign a value x of the random variable X representing the number of computers purchased by the retailer which are slightly defective.

z=0 with probability (5/11)(4/10)=2/11.
z=1 with probability (5/11)(6/10)+(6/11)(5/10)=60/110 or 6=2/11
z=2 with probability (6/11)(5/10=3/11
The sum of the three probabilities is 1.
