Question

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

Answer 1

first of all assume that  probability of winning of  C is "X"
So according to the question probability of Winning of B will be 2X
and then again the probability of  winning of A  will be=  2*2X =4X
Also in this case of probability  X+2X+4X = 1
 hence by solving it                  7X=1 
So the X=1/7

Which means the probability  for horse C will be 1/7
The the probability of winning of horse B will be = 2/7
And the winning of probability  for horse A will be = 2*2/7 = 4/7

 

Answer 2

Explanation:

first of all assume that probability of winning of

C is "X" So according to the question probability of Winning of B will be 2X

and then again the probability of winning of A

will be= 2*2X=4X

Also in this case of probability X+2X+4X = 1 hence by solving it 7X=1

So the X=1/7

Which means the probability for horse C will

be 1/7

The the probability of winning of horse B will

be = 2/7

And the winning of probability for horse A will be = 2*2/7 = 4/7
