Answer:
1/7
Step-by-step explanation:
Let probability that C wins be 'p', then probability that B wins will be 2p and probability that A wins will be 4p.
Also, p+2p+4p=1
So, p=1/7
ALL THE BEST DEAR.
rreexx123:
tq
but why do we add them
COZ we r finding p i.e. C
what is c?
so,we have add the probability of A+B+C
ok
but how do we know they are equal to 1?
C is the probability of C horse winning
ok
coz by ques A is twice greater than B and B is again twice greater than C Therefore,A=2p,B=4p&C=p

Answer:
p(C)=1/7.
Step-by-step explanation:
let the p(C)=x.
Therefore, p(B)=2x
and p(A)=2(2x)
the horse C is winning,
therefore probability of winning is 1.
p(A)+p(B)+p(c)=1
Now, by substituting their values
2(2x)+2x+x=1
4x+2x+x=1
7x=1
x=1/7
therefore, the probability of winning of horse C is 1/7 ,and of B is 2/7 and of A is 4/7.
Hope it will help you
