In the following probability distribution, the random variable x represents the number of activities a parent of a K to 5th-grade student is involved in. Complete parts (a) through (f) below. X 0 1 2 3 4 P(x) 0.053 0.057 0. 185 0.265 0.440 . . . (a) Verify that this is a discrete probability distribution. This is a discrete probability distribution because the sum of the probabilities is 1.0| and each probability is greater than 0 and less than 1. K
