This doesn't make much sense to me. What do you mean by "Expectancy of winning $N$ consecutive times?$ Do you mean the probability of winning $N$ consecutive times? –  Brett Frankel Apr 29 '12 at 3:03

Maybe I'm missing something, but if the payout for each round won is $\$5$, shouldn't the payout for $N$ wins in a row be $\$5N$?
