A shipment of 5 computers contains three that are slightly defective. A retailer receives three of these computers at random. List the elements of the sample space 5 using the letter D and N for defective and none defective computers respectively. To each sample point assign a value of X of the random variable X representing which is slightly defective.
Let "X=" the number of slightly defective computers
"3N, 0D"
"X=0"
This combination does not exist, because "5-3=2<3." A retailer can receive at most 2 normal computers.
"2N, 1D"
"X=1"
"1N, 2D"
"X=2"
"0N, 3D"
"X=3"
Sample space:
"S_X=\\{{1,2,3}\\}"
