Answer the following questions on probability. Port is o is a sample solution. Solve for b and c. f 4 points each for a total of 8 points) A coin is tossed four times. Each time the result H for heads or T for tails is recorded. An outcome of H H Ti" means that heads were obtained on the first two tosses and tails on the second two. Assume that heads and tails are equally likely on each toss. a. How many distinct outcomes are possible? In each of the four tosses there are Mo possible results: Either a head {H ) or a tail (T) is obtained. Thus. by the multiplication rule. the number of outcomes is 2-2-2 -2 = 2' = 16. b. What is the probability that exactly two heads occur? c. What is the probability that exactly one head occurs
