A and Bare each rolling a fair, six-sided die. They roll their dice simultaneously, individually keeping a sum until someone reaches 100; whomever reaches 100 first wins. (If they reach 100 on the same roll, it's a tie.)

A's die has sides 1, 2, 3, 4, 5, and 6. B's die has sides 1, 1, 1, 6, 6, and 6. Who is more likely to win?

Thanks Gaurav for sharing...
