Determine whether the following is a probability distribution. If not, identify the requirement that is not satised. 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. 0.25 0.26 0.22 0.11 0.0? 0.03 0 1 2 3 4 5 Not a probability distribution. The sum of the P(x)'s is 1.00. Not a probability distribution. The sum of the P(x)'s is not 1, since 0.94 $1.00. Not a probability distribution. One or more of the P(x) values is not between 0 and 1.00. This is a probability distribution. 9
