Answers
Given : There are three horses in a race A,B and C . probability of A is as twice as B,and probability of B is as twice as C
To find : Probability of winning of each horse
Solution:
Let say Probability of winning Horse C = P
probability of B is as twice as C
=> Probability of winning Horse B = 2P
probability of A is as twice as B,
=> Probability of winning Horse A = 2 (2P) = 4P
P(A) + P(B) + P(C) = 1 as there are 3 horses only
=> 4P + 2P + P = 1
=> 7P = 1
=> P = 1/7
Probability of winning Horse A = 4/7
Probability of winning Horse B = 2/7
Probability of winning Horse C = 1/7
