5) Random variable X is defined as
X: Number of Democrats selected.
Senators are being selected from the group of 10 Democrats and
20 Republicans so there are total 10 Democrats. It is possible that
among Ten senators selected there can be zero Democrats or at most
there can be 10 Democrats so possible values of X are from 0 to 10
including zero and ten. So, possible values of X are [x: 0
x
10].
X can take any value from 0 to 10.

Problem 6: Ten manufactured parts are randomly selected from a batch where it is believed that the percent nonconforming is 15%. It is important to determine the probability that exactly two out of 10 manufactured parts will be nonconforming. If the random variable X represents the number of nonconforming parts; What is the probability that exactly two parts are nonconforming? What is the probability that less than two parts are nonconforming?
