You are given a red coin and a blue coin. Both coins have the number 1 on one side and the number 2 on the other side. You flip both coins once (independently of each other) and take the sum of the two results. Define the events A B C = "the sum of the results equal 2", "the sum of the results equals 3", "the sum of the results equals 4". Assume both coins are fair. Determine Pr(A), Pr(B), and Pr(C). Show your work. Let p and q be real numbers with 0 < p < 1 and 0
