ine Whether the following is a probability distribution. If not, identify the requirement that is not satisfied. Remember that you have to check the two requirements for discrete probability distributions. If a person is randomly selected from a certain town, the probability distribution for the number, x, of siblings is as described in the accompanying table. P(X) 0. 0.25 0.32 0.22 3. 0.10 4 0.05 0.04 Not a probability distribution. The sum of the P(x)'s is not 1, since 0.98 1.00. This is a probability distribution
