Ha, think logically, and with simpler numbers.

A one in two chance of winning in one year gives either a win or a loss

a one in two chance in the second year gives either a win or a loss, so we have four possabilities over two years, win win, loss loss, win loss, or loss win. A one in four chance of winning both years. So it is (technically speaking) a one in 7,499 times 7,499 = one in 56,235,001 chance of winning both years.

The chances of winning in either year remain the same, even for the winner of the first year. Toss a coin, it comes up heads 10 times, whats the odds for the 11th throw. A head or a tail, one in two.

A nice trick for xmas parties.
