Eight tennis players (call them A,B,C,D,E,G,F,H) are randomly assigned to start positions in a ladder tournament. Initially, position 1 plays position 2, position 3 plays 4, 5 plays 6 and 7 plays 8. Second round has 2 matches: winner of (1,2) match plays winner of (3,4), and winner (5,6) plays winner(7,8). The winners of the two 2nd round matches play each other in the final match. Player A wins against any of the others. Player B always beats any opponent except player A. What is the probability that player B wins the 2nd place trophy in the final match?

i dont think so .. well ,anyway i dont hav the OA .
my approach : take two sets (1,2,3,4) (5,6,7,8)
two cases --> A and B in same set ; A and B in different set
fav.case --> A and B in diff.set so that they wud end up meeting in the finals .
so prob.--> 1/2

@rubikmath even i thought that it woulf be 1/2 only.. but then I took the probability of A&b; being in set(1,2,3,4) and then deducting it by 1 :)
@rubikmath bhai dekh
8^8 tarike se arrange kar sakta hain theek hai .
ab salla bahar na ho final tak uske liye do set hone chahie jismein ek mein a ho aur dusre mein b inka kuch karna padega tooh pata

why wud v be concerned with arrangement of others ?? A is gonna win anyway .
only condition is B shudnt meet him til the finals
OA is 4/7
i think after A 's position is fixed , find B 's favourable position .
