Q#3 a) At the entrance to a casino, there are two slot machines. Machine A is programmed so that in the long run it will produce a winner in 10% of the plays. Machine B is programmed so that in the long run it will produce a winner in 15% of the plays. (i) If we play each machine once, what is the probability that we will win on both plays? (ii). If we play each machine once, what is the probability that we will lose on both plays? (iii). If we play each machine once, what is the probability that we will win on at least one play?

a) At the entrance to a casino, there are two slot machines. Machine
A is programmed so that in the long run it will produce a winner
in 10% of the plays. Machine B is programmed so that in the
long run it will produce a winner in 15% of the plays. (i) If we
play each machine once, what is the probability that we will win
on both plays? (ii). If we play each machine once, what is the
probability that we will lose on both plays? (iii). If we play each
machine once, what is the probability that we will win on at least
one play?

Dividing a JackpotA game between two players consists of tossing a coin. Player A gets a point if the coin shows heads, and player B gets a point if it shows tails. The first player to get six points wins an 8,000 jackpot. As it happens, the police raid the place when player A has five points and B has three points. After everyone has calmed down, how should the jackpot be divided between the two players? In other words, what is the probability of A winning and that of B winning if the game were to continue? The French Mathematician Pascal and Fermat corresponded about this problem, and both came to the same correct calculations though by very different reasonings. Their friend Roberval disagreed with both of them. He argued that player A has probability 34 of winning, because the game can end in the four ways H, TH, TTH, TTT and in three of these, A wins. Robervals reasoning was wrong. a Continue the game from the point at which it was interrupted, using either a coin or a modeling program. Perform the experiment 80 or more times, and estimate the probability that player A wins. bCalculate the probability that player A wins. Compare with your estimate from part a.
