Question: what is the probability of getting a card of spade or an ace?
Answer: You should know that a standard 52-card deck is made up of four suits of 13 cards each. This means that there are 13 spades and 4 aces (the Ace of Spades is both). So the probability of drawing any spade is 1 in 4, and the probability of drawing any ace is 1 in 13.
