`P_1, P_2, P_3,...........,P_8 are 8` players of equal strength who play with each other in a knockout tournament. The probability that `P_1` wins against `P_2 and P_3` to reach the final and also wins the tournament is p, then 42p is equal to

If 2=p^(3) , then 8p must equal

If P = {2, 3}, then P xx P is equal to

If P = {2, 3}, then P xx P is equal to

5 players of equal strength play one each with each other. P(A)= probability that at least one player wins all matches he (they) play. P(B)= probability that at least one player losses all his (their) matches.

If A and B play a series of games in each of which probability that A wins is p and that B wins is q=1-p. Therefore the chance that A wins two games before B wins three is

Eight players P_1, P_2, P_3, ...........P_8 , play a knock out tournament. It is known that whenever the players P_i and P_j , play, the player P_i will win if i lt j . Assuming that the players are paired at random in each round, what is the probability that the players P_4 , reaches the final ?
