probability

Engineering Entrance , JEE Main , JEE Advanced , Mathematics , Algebra

A,B,C are three horses in a race.the probability of A to win the race is twice that of B,and the probability of B is twice that of C.what are the probabilities of A,Band C to win the race?

i've found out P(A)=4/7

P(B)=2/7

P(C)=1/7.

can you plzzz... tell me what are the prob.of A,B,C to win race?what does this mean?

LET PROB OF C IS X THEN P(B)=2X.P(A)=4X...ONE OF THEN WINS SO PA+PB+PC=1. X=1/7. PA=4/7,PB=2/7
