Calculates the probability of two (or more) events that happen independently of each other, such as flips of a coin or picking cards from a deck, when the first is returned before the second is drawn.

P(A and B) = P(A) x P(B)

For example, the probability of drawing an ace two times in a row when the first is returned to the deck is 1/13 * 1/13 or 1/169.
