Consider a standard deck of 52 cards, with four suits: Let event $A=$ card is an Ace Let event $B=$ card is from a red suit What is probability of getting a card being ace or red suit?

Step 1 ：Find the probability of drawing an Ace: \(P(A) = \frac{4}{52}\)

Step 2 ：Find the probability of drawing a red card: \(P(B) = \frac{26}{52}\)

Step 3 ：Find the probability of drawing a red Ace: \(P(A \cap B) = \frac{2}{52}\)

Step 4 ：Calculate the probability of drawing a card that is either an Ace or a red card: \(P(A \cup B) = P(A) + P(B) - P(A \cap B) = \frac{4}{52} + \frac{26}{52} - \frac{2}{52}\)

Step 5 ：\(P(A \cup B) = \frac{28}{52}\)

Step 6 ：\(\boxed{P(A \cup B) \approx 0.5385}\)
