5. The amplitudes of two signals X and Y have joint pdf: Ísy(x,y)-kx(1-x)y, x, y є (0, 1). for (i) Find the k and the joint C 

5. The amplitudes of two signals \(X\) and \(Y\) have joint pdf:

$$ f_{X, Y}(x, y)=k x(1-x) y, \text { for } x, y \in(0,1) \text { . } $$

(i) Find the \(k\) and the joint CDF.

(ii) Find the marginal pdfs and CDFs.

(iii) Find \(P\left[Y<X^{1 / 2}\right]\).
