Two cards are drawn from an ordinary deck of cards, and the first is not replaced before the second is drawn.
What is the probability that one card is an ace and the other is a king

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
4/52 * 4/51 = ?
Either-or probabilities are found by adding the individual probabilities.
But it can be A,K or K,A, so multiply the above answer by 2.
