Suppose that an experimenter tossed three balanced coins. He defined X₁, to denote the number of heads and X₂, is to denote the amount of money won on a daily lotto bet iSouth Africa in the following manner. If the first head occurs on the first toss, R1 (one rand) is won. If the first head occurs on toss 2 or on toss 3, R2 or R3 is won respectively. If no heads appear, the R1 (that is, win -R1) is lost. Find i) the joint probability function of X₁ and X2. ii) the probability that less than 3 heads will occur and the student will win R1 or less.
