Three horses a, b,and c are in a race, a is twice as like to win as b, and b is as twice as like to win as c, what are their probabilities of winning?

Answer 1

let probability of c winning = p, then for b= 2p and a= 4p. as there r 3 participants so these events r mutually exclusive (that one of them must win)
p + 2p + 4p = 1
