    Help with joint distributions?

    Homework Statement Suppose X and Y have joint density f(x,y)=2 for 0<y<x<1. Find P(X-Y>z) According to the textbook the answer should be (1-z)^{2}/2 Homework Equations The Attempt at a Solution \int \int 2dxdy for x=[0, z+y] and y=[0,1] =\int 2(z+y) dy =2z+1 since we...

    Transforming functions of random variables (exponential->Weibull)

    Homework Statement Suppose X has an exponential with parameter L and Y=X^(1/a). Find the density function of Y. This is the Weibull distribution Homework Equations The Attempt at a Solution X~exponential (L) => fx(s)= Le^(-Ls) Fx(s)=P(X<s) = 1-e^(-Ls)...
