If you choose to look the answer up in advance, you should at least try to determine the answer on your own first. They want to gauge your process for determining the answer in real time.

"Place 1 black marble in one bowl, and place the rest of the marbles 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."
