    Computing probability




    fX(x)= (3/8)*x*x 0<x<2
    fY(y)= 1/x x<y<2x

    P(1<y<3)

    Now how do i do this ?

    Do i have to combine them ?

    I have absolutely no clue

    Re: Computing probability


    You are given a marginal pdf f_X and a conditional pdf f_{Y|X=x}


    1. How to obtain the joint pdf f_{X,Y} from these two?
    2. How to obtain the marginal pdf f_Y from the joint pdf?
    3. How to compute the required probabiltiy \Pr\{1 < Y < 3\} once the marginal pdf f_Y is obtained?
