This prоblem hаs twо independent Bernоulli rаndom vаriables X and Y, which means they can each be either zero, or one. The probabilities defining the Bernoulli random variables are given as where [p], and [q]. Next we define two other new random variables Z and W. Let and . Find . Hint: Identify all X,Y pairs that would yield Z=1 and W=1, and add up their probabilities.
