Chapter 7.2, Problem 17E

Let the random variables X and Y have the probability distributions listed in Table 15. Determine the probability distributions of the random variables in Exercises 13–20.

Table 15

K	$\mathrm{Pr}\left(X=k\right)$	k	$\mathrm{Pr}\left(Y=k\right)$
0	.1	5	.3
1	.2	10	.4
2	.4	15	.1
3	.1	20	.1
4	.2	25	.1

$\frac{1}{5}Y$
