3 cars A B C are in the race A is twice as likely to win as B and B

ans B'S probability to win =310.
let c's winning probability to win is =x
then b=3x
a=6x
then b's winning probability =3x(x+6x+3x)
b=310.

let B's ability is x
A is twice as likely to win as B,so A's ability is 2x
C's ability is x/3
A :B: C --> A :B :C
2x:x :x/3 --> 4x:3x :x
so probability that B will win is 3x/(4x+3x+x)=3x/10x=3/10(ans)

ans is 3/10
p(A)=2p(B)
p(B)=3p(C)
so,A's prob is 6/10,B's prob is 3/10,C's prob is 1/10
since,p(S)is 10.

here, A is twice as likely as B so A:B=2:1
and B is thrice as likely as C so B:C=3:1
then A:B:C=6:3:1
from this B's probability is 3/10

@parag : plz tel me if asked abt prob of a than wat will b the ans ??

LET C - X , B - 3X, A - 6X

TOTAL PROBABILITY = 1
A + B + C =1
10 X =1
X = 1/10 SO, B'S 3X = 3/10

3 cars A, B & C are in the race. A is twice as likely to win as B and B is thrice as likely to win as C. what is probability that B will win, if only one can win the race ?
a) 1/2 b) 2/5 c) 3/10 d) 1/10
