7. (Sec 5.1) Suppose the joint pdf of two rvs X and Y is given by
152y for 0
0 otherwise
< y<1
f(r, y)

(b) What is P(X Y < 1)?
(c) What is the probability that X is greater than .7?
(Hint: it might help to find the marginal pdf first)

If X is exponentially distributed with parameter λ and Y is uniformly distributed on the interval [a, b], what is the moment generating function of X + 2Y ?
Suppose that n observations are chosen at random from a continuous pdf fY(y). What is the probability that the last observation recorded will be the smallest number in the sample? I asked this question earlier today, but didn't quite understand all of the response. P(y1<=yn)p(y2<=yn) and so on was used, but shouldn't the yn be listed first in the inequality since we want to know if yn is the smallest?
