Hi there!
Since a deck of cards in total has 52 cards, and there is 4 different sets of cards, which are hearts, clubs, spades and diamonds, we divide 52 by 4 to see how many cards are spades. After that, though, we are not finished.
52 ÷ 4 = 13. So, there are 13 spades in the deck.
Now, since 13 is just 1/4 of the number of cards you have, there is a 25% chance you will pull out a spade from the deck of the 52 cards.
Why?
Because 1 divided by 4 = 0.25, or, 25%.
Hope this helps!
