hree balanced coins are tossed independently. One of the variables of interest is Y₁, the number heads. Let Y₂ denote the amount of money won on a side bet in the following manner. If the st head occurs on the first toss, you win $1. If the first head occurs on toss 2 or on toss 3 you in $2 or $3, respectively. If no heads appear, you lose $1 (that is, win -$1). Find the joint probability function for Y₁ and Y₂. What is the probability that fewer than three heads will occur and you will win $1 or less? [That is, find F(2, 1).]
