if you laughed after seeing this answer pleeeeeease mark this answer as brainlist

Answer 2

a=4/7. b = 2/7 c= 1/7

Step-by-step explanation:

Let the probability of winning of horse C is x.

then probability of winning B is 2x and probability of winning A is 4x.

Also total probability of winning is 1.

So P(A)+P(B)+P(C)=1

⇒x+2x+4x=1⇒x=

7

1

Hence probability of winning of horses A,B, and C are
