Kindly help me in Probability

A restaurant operates both a drive-in facility and a walk-in facility. On a randomly
selected day, let X and Y respectively be the portions of the time that the drive-in and
walk-in facilities are in use, and suppose that the joint density function of these
random variables is:
, =
23
+2, 0 ≤  ≤ 1,0 ≤  ≤ 1
0, ℎ

a. Find the marginal density function of X and Y.
b. Find the probability that the drive-in facility is busy less than one-half of the
time

Hi sumair_bano;

I am not saying I was going to get this, cause density functions mess me up but it would help to be able to see the problem, My browser is unable to see what those characters are.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
