Determine the repartition of $Y$

27 Views Asked by At

How should i approach the following problem ?

Let $Y$ be a random variable , $Y =\sqrt[n]{\prod_{k=1}^{n}X_k} $, where $(X_k)_{k=\overline{1-n}} \in U(0,1)$, are independent random variables.

I have absolutely no ideea how i should solve it? Hints / A solution would be really appreciated!
