Can anyone help me on the following Pls?

The random variable X has p.d.f given by

f(x) = x/2 0£ x £ 2

0 otherwise

(a) Find the c.d.f of X, FX(x).

The random variable Y = X2 and takes values over the range

0 £ y £ 4.

(b) Show that P(Y < y) = P(X £ Öy).

(c) Hence show that the c.d.f of Y, FY(y) is given by

FY(y) = 0, y < 0

y/4, 0 £ y £ 4

1, y > 4
