Honestly, you can believe WW all you want, but the simple fact of the matter is, he is wrong. This is a widely known Probability problem that occurred in the mid 70's amongst mathematicians around the world. The answer I stated is based on the logic and reasoning of the smartest people's combined efforts inthe world. Take it or leave, but its true.

If you were take an introductory Error, Uncertainty, and Probability course in college you would see why he is wrong. Also, if it so appeases you, check out a Stochastic Systems course, and you will surely come across this problem.
