HW 1.y.(Yutnori)
Yutnori is played by 2 (groups of) players on a gameboard with pieces thatmove around. Each player takes turns throwing yut sticks - each stick hastwo sides, round and flat, which makes the stick roll. Five combinationsare possible with yut sticks: do, gae, geol, yut and mo. A player achievinga yut or mo is allowed to roll again. Combinations and the number ofmoves they allow on the gameboard are presented in Figure 3 (flat sideup is blank and round side up is filled with x-es).
Assuming each of the 4 Yut sticks falls on both of its sides with equalprobability, what is the probability that:a) you roll a yut?b) you roll a geol ?c) you get a second roll?d) you move 6 spaces in your first turn?In reality, a typical Yut stick is designed so that the probability of flat sidefacing up is around 60%. Try to think of what the previous probabilitieswould be in this case.

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)
