Question

In a one race A,B and C are three horses. The probability of A is a twice that of B and B is twice than C ,what is the probability of winning them ?

Answer 1

A=2B.......1
B=2C.......2
from 1 and 2 we get
A=4C
BUT WE KNOW THAT
A+B+C = 1
BY PUTTING VALUE OF A ,B ,C
4C +2C + C= 1
SO PROBABILITY OF C= 1/7
AS WE KNOW
B=2C
B= 2/7
AND A= 2B
SO
A= 4/7
HENCE THE PROBABILITY OF A HORSE IS MORE THAN B AND C
SO A HORSE WIN THE RACE
