Answered by drwls
It depends upon how much is bet each time.

If you bet 1 dollar each time, there is a 26/38 = 0.6842 chance you will lose it,and a 12/38 = 0.3158 chance you will win $2, for a dollar gain of 0.6316.

There is a net loss expectation of 0.6842 - 0.6316 = 0.0526 per toss. That would be $5.26 after 100 tosses.
