Question

Let X and Y be independent positive random variables. Let Z = X/Y.In what follows, all occurrences of x, y, z are assumed to be positive numbers. 1. Suppose that X and Y are discrete, with known PMFs, px and py. Then, Pzy (z | y) =
Required:
What is the argument in the place of the question mark?

Answer 1

Answer:

Px(?) = Px ( yz )

Step-by-step explanation:

Pzy (z | y) = Px(?)

Given that ; Z = X/Y and occurrences ; x,y,z  are all positive numbers

also assuming X and Y are discrete

In place of the question mark

Px(?) = Px ( yz )

attached below is the detailed solution
