1.) A state lottery consists of selecting balls from four containers, each consisting of balls numbered 0-9. Suppose you win if any permutation of your chosen four numbers win. Find the probability of winning if the four digits you chose were:
(a) 2, 3, 4, 5.
(b) 2, 3, 4, 4.
(c) 2, 2, 4, 4.
2. )Two friends choose to have a best of nine video game battle with the winner being the first player to win five times. A possible outcome would be BBABAABB where player A wins the3rd, 5th and 6th games while player B wins games 1,2,4,7, and 8. There is no 9th game because player B has already won 5 times. How many different orders are possible if the battle goes
(a) 6 games?
(b) 9 games?
3.) At the end of the semester, 20 students fill out a class evaluation for a professor. They can rank him on a scale of 1-5, where 1 is terrible and 5 is excellent. How many different ratings combinations are possible?
