4.When two balanced dice are rolled, there are 36 possible outcomes. Find the probability that either doubles are rolled or the sum of the dice is 4.

5.A committee of two people is to be formed. The two people will be selected from a list of four possible committee members. A simple random sample of two people is taken, without replacement, from the group of four people. If the four people are represented by the letters A, B, C, and D, determine the probability that C or D are not included in the sample.
