Just provide for part a just part a

a) Suppose that X and Y are two independent continuous random variables with ti
following probability functions
f(x) = 2x for 0<x< 1
f(y) = 3y²
for 0<y<1
i. Find the probability P(X + Y < 0.5)
ii. Find the covariance (X,Y).
iii. Find the conditional probability P(X < 0.2/Y < 0.25)
b) The two dimensional random variables (P,Q) has a joint density function
1+p +q + cpq
f(p, q)
c + 3
.e-(p+q),
p 2 0, q 2 0
where c > 0 is a constant.
i. Find the probability P(P < 1)
ii. There exists exactly only one value
What is such a value?
c in order that P and Q are independer
