Problem 22E

Here are two random variables that are uncorrelated but not independent. Let X and Y have the following joint probability mass function:

a. Use the definition of independence on page 141 to show that X and Y are not independent (in fact $$Y=|X|$$, so Y is actually a function of X).

b. Show that X and Y are uncorrelated.

Equation Transcription:
