This is a famous paradox which has caused a great deal of argument and disbelief from many who cannot accept the correct answer. Four balls are placed in a hat. One is white, one is blue and the other two are red. The bag is shaken and someone draws two balls from the hat. He looks at the two balls and announces that at least one of them is red. What are the chances that the other ball he has drawn out is also red?

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?
