Question 830395: A cube has four of its faces blank, one face is marked 5 and the other is marked 6. In a game involving throwing this cube, a person is said to have a success, if he throws a numbered face. Two persons A and B participated in this game. A throws the cube thrice while B throws it once. Find the ratio of A's chance of success to that of B.

A cube has 6 faces. 4 blank, 2 numbered.
P(success)=2%2F6=1%2F3
P(success,A)=%281%2F3%29%281%2F3%29%281%2F3%29=1%2F27
P(success,B)=1%2F3
P(success,A)/P(success,B)=%281%2F27%29%2F%281%2F3%29=1%2F9
