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) 0.225 0.063 0.117 0.176 0.419 Question content area bottom Part 1 (a) Verify that this is a discrete probability distribution. This is a discrete probability distribution because the sum of the probabilities is enter your response here and each probability is greater than or equal to 0. less than or equal to 1. between 0 and 1, inclusive. greater than 0 and less than 1.

(B) Graph the discrete probability distribution.

(c) Compute and interpret the mean of the random variable x

d) compute the standard deviation of the random x
