Question

A and B throw a pair of dice alternately. A wins the game, if he gets a total of 7 and B wins if he gets a total of 10. If A starts the game, then find the probability that A wins.

Answer 1

The probability of A winning is 2/ 3 or 66.67 %

See the images for full solution.

In short , total number of combinations by a pair of dice is 36.

in 6 out of 36 combinations , 7 is the sum.

in 3 out of the 36 combinations , 10 is the sum .

Therefore , the probability of A winning is ratio of

6/36 : 3/36

= 6 : 3

Which when converted in Percentage form will be ,

6 / (6+ 3) * 100

6/9 * 100

= 66.67 %
