`8` players `P_1, P_2, P_3, ,P_(8)` play a knock out tournament. It is known that all the players are of equal strength. The tournament is held in three rounds where the players are paired at random in each round. If it is given that `P_1` wins in the third round.if p be the be the probability that `P_2` loses in second round ,yhen the value of 7p is
