In: Statistics and Probability
Suppose that the joint probability density function of ˜ (X, Y) is given by:´ f X,Y (x,y) = 4x/y3 I(0.1)(x), I (1, ∞)(y).
Calculate
a) P(1/2 < X < 3/4, 0 < Y ≤ 1/3).
b) P(Y > 5).
c) P(Y > X).
Given is:
a)
Here we can see the y values are bellow 1
so f(x,y)=0
C)
The limit of this function is
The y value below is the f(x,)=0
So,
