enter the success ratio of A in the form (x,y) : 4 5
enter the success ratio of B in the form (x,y) : 3 4
enter the success ratio of C in the form (x,y) : 2 3

when any two hit the shot
the probability in this case is 0.433333

when all three review the book
the probability in this case is 0.4

the required probability is 0.833333
