From a standard 52-deck of cards, find the probability of drawing a spade, then a heart.

In a standard deck of cards, there are 4 types of cards: spades, hearts, clovers, and diamonds.

On your first draw, you have a 25% chance to get a spade, because 1/4 = 25%.

If you got a spade on your first draw, then the chance of you getting a heart on your second draw is 13/51.

This is because you already took a card from the deck, and there are 13 cards that are hearts.

When we multiply 1/4 and 13/51, we get 13/204 as an exact answer.
