"Place one black marble in one bowl, and place the rest in the other bowl (49 blacks and 50 whites). This way, you begin with a 50/50 chance of choosing the bowl with the single black marble! If you choose the other bowl, you still have a nearly 50/50 chance at picking one of the 49 black marbles."
