Answer:
Probability breaks down to this basic formula:
desired outcome
total possible outcomes
Also, you need to know there are 13 spades in a deck of cards.
So, on your first draw, the chances of getting a spade are:
13 (desired outcome: pick one of the 13 spades)
52 (total possibilities: 52 cards in the deck)
But on your second draw, if you don't replace the card, your chances of getting a spade are:
12
51
because you only have 12 spades left, and 51 cards total.
Then, on your last draw, the chances of getting a spade are down to:
11
50
Since each of these probabilities depend on each other, you multiply them up to get your overall probability:
13 * 12 * 11 = 1,716
52 51 50 132,600
This reduces, or you can just divide to get a decimal.
