Given the probability distributions shown to the​ right, complete the following parts.

a. Compute the expected value for each distribution.

b. Compute the standard deviation for each distribution.

c. Compare the results of distributions A and B.

Distribution A:    Distribution B:

X P(X)    X P(x)

0 0.04 0 0.48

1 0.09    1 0.25

2 0.14    2 0.14

3 0.25    3 0.09

4 0.48    4 0.04

Round to three decimal places, compare the distributions for A and B
