**CONTENTS UNIT – II TWO DIMENSIONAL RANDOM VARIABLES**

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= â‹… XY when X and Y are discrete or f (, ) ( )xy f x f y=â‹… XY when X and Y are continuous. If the conditions are not satisfied for all (x, y) then X and Y are dependent. Slide 10 Stat 110A, UCLA, Ivo Dinov More Than Two Random Variables If X 1, X 2,â€¦,X n are all discrete random... The sum of two independent Poisson random variables with parameters l 1 and l 2 is a Poisson random variable with parameter l 1 + l 2. 292 Example: Let random variables X 1 and X 2 have the joint p.d.f. as find the p.d.f. of the random variable Y = Sol: Since y decreases as x 2 increases and x 1 hold constant, we can find a joint density of X 1 and Y and then use transformation technique to

**CONTENTS UNIT – II TWO DIMENSIONAL RANDOM VARIABLES**

The Bivariate Normal Distribution This is Section 4.7 of the 1st edition (2002) of the book Introduc- tion to Probability, by D. P. Bertsekas and J. N. Tsitsiklis. The material in this section was not included in the 2nd edition (2008). Let U and V be two independent normal random variables, and consider two new random variables X and Y of the form X = aU +bV, Y = cU +dV, where a,b,c,d, are...That is, two random variables are independent if their joint probability distribution function factors into the marginal distributions. A certain joint probability density function is given by the formula
