HW 1.w. (Special game)The atmosphere has heated up and a fight erupted! There are n + 1players and somebody threw the first punch. Once a person is punched,they punch another person in the group at random. What are the oddsthat after m iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?Now take it up a notch: imagine the first person punched N other peopleat random, and once someone gets punched, they punch another N peoplein the group at random, and so on. Again, what are the odds that afterm iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?
Q1. A chest of drawers has 3 drawers. Each drawer has 2 boxes. The boxes of one
drawer contain a silver coin in each respectively, the boxes of another a gold coin in
each box, and the boxes of the third drawer a gold and a silver coin, respectively. A
drawer is selected at random and a box from the drawer is selected at random and
opened. The coin is found to be silver. What is the probability that the coin in the
other box is gold? (Harder Problem)
