Probability of a 8 or King Jasmine Buckner Ellesse Rougier Period 7A Integrated 2 October 17, 2006
Key Skills Use the Addition of Probabilities Principle. 13.2 Counting the Elements of Sets A card is drawn at random from a deck of 52 cards. Find the probability that the card is a 8(8) OR a king card (k). P( 8or k) = P(8) + P( k ) – P( 8 k) 4 52 = 8 = 0.154 = 4 52 + 0 – # 8s+ # Kings– # 0
Information on our problem We used disjoint to solve our problem because our problem had basically nothing in common. I mean they might have had some of the same symbols like diamond, club, heart, or spades but our problem didnt ask for that it asked for the number of 8s and the number of kings. For Example: 13.2 Counting the Elements of Sets
