compietely ed wiwaterQ.16.Three hourses A, B and C are in a race, A is twice as like to win as B and B is twice as like to win as Cwhat are their probabilities of winning?

Answer»

First of all assume that probability of winning of C is "X"So according to the question probability of Winning of B will be 2Xand then again the probability of winning of A will be= 2*2X =4XAlso in this case of probabilityX+2X+4X = 1

Hence by solving it 7X=1 So the X=1/7

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