Two individuals, A and B, are finalists for a chess championship. They will play a sequence of games, each of which can result in a win for A, a win for B, or a draw. Suppose that the outcomes of successive games are independent, with P(A wins game) = 0.3, P(B wins game) = 0.2, and P(draw) = 0.5. Each time a player wins a game, he earns 1 point and his opponent earns no points. The...

Question 6 Write the correct values in the boxes. For this question, working is not required and will not be marked. Two of many kinds of bets you can make on a horse race are Win' and 'Place'. In each of these you nominate a horse, say 'Neddy', pay some money (your 'stake) and maybe get some money back (your 'payout'). The payout, if paid, is stakexodds, where 'odds is a number greater than 1 specified by the betting agency....
