1) Let X have the p.d.f. f(x) = 4x^3 , 0<x<1

Find the p.d.f. of Y = X^2

2) Let x have a gamma distribution with &#61537;=3 and &#61553; = 2

determine the p.d.f. of Y=X^2.

3) The P.d.f. of X is f(x) = &#61553; x^(&#61553;-1), 0<x<1 , 0<&#61553;<&#61605;. Let Y=-2&#61553; lnX. How is Y distributed?
