Let A = {b, c, 1, 2, 3}, B = {a, d, e, 4}, C = {e, 4}, D = {a, d, e, 2} and U = {a, b, c, d, e, 1, 2, 3, 4} Find the following: a) A C b) A D c) B' D d) C D d) If all elements in U are equally likely to occur then find P(B) 25 runners are competing in a race. The top three will be selected to go to the Olympics. How different groups of three can go to the olympics? (no ties) 25 runners are competing in a race. First place gets a gold medal, second silver, and third bronze. In how many different ways can the medals be awarded? (no ties) A license plate with 5 characters is being made. The first three must be letters (A - Z) and the last two must be numbers (0 - 9). How many different license plates are possible? How many license plates would be possible (from problem 4) if the first two characters must "AZ"? Timmy has 3 red squares and 2 blue squares that he must put in a line. If the squares of the same color are indistinguishable from each other, then how many ways can he do this?
