Question

Three horses A B C are in a race A is twice as likely to win as B and B is twice as likely to win as C. What are the probability of winning

Answer 1

A has a four out of seven chance of winning. B has a 2 out of seven chance of winning. C has a one out of seven chance of winning.

Answer 2

Answer:

P(s) = 1/7

Step-by-step explanation:

Let the probability of winning of C = x

then the probability of winning of B = 2x

and the probability of winning of A = 2.2x= 4x

as we know that sum of total probability is 1

now, p(a)+p(b)+p(c)= 1

4x + 2x + x = 1

7x=1

x=1/7
