Let X be the prive of a meal at a local diner X 810and 12 a

Let X be the prive of a meal at a local diner( X = $8,$10,and $12) and let Y be the amount of tip left per meal (Y = $1.50,$2 or $2.50). the joint probability function of X and Y is given by

a. Find f(X = 10, Y=2) and interpret what this value represents.

c. Find the marginal distributions of X and Y.

d. Determine if X and Y are independent Random Variables or not. Explain why or why not.

f(x,y)	Y=1.50	Y=2.00	Y=2.50
X=8	.3	.12	0
X=10	.15	.135	.025
X=12	.03	.15	.09
