Find the joint distribution of two independent random

Test two integrated circuits. In each test, the probability of rejecting the circuit is p. Let X be the number of rejects (either 0 or 1) in the ?rst test and let Y be the number of rejects in the second test. Find the joint PMF PX,Y (x,y). Problem 4.2.3 Solution Let r (reject) and a (accept) denote the result of each test. There are four possible outcomes: rr,ra,ar,aa. The sample tree is p

zInstructor: Ivo Dinov, Asst. Prof. In Statistics and Neurology z Two random variables X and Y are said to be independent if for every pair of x and y values p(, ) ( ) xy p x p y=? XY when X and Y are discrete or f (, ) ( )xy f x f y=? XY when X and Y are continuous. If the conditions are not satisfied for all (x, y) then X and Y are dependent.
