In a game of bridge, choose 13 cards from a deck at random (use equally likely probability). Question: What is the probability you get NO spades? What is the probability you get no card higher than 9 (with aces considered high cards)? What is the probability neither of these occur?
I just wanted to know if I'm on the right track for this question, to calculate the probability that neither event occurs would it be equal to $P((A ∪ B)^c)$?
