Suppose that four cards are drawn successively from an ordinary deck of 52 cards, with replacement and at random. What is the probability of drawing at least one king?
Answer from the book: 0.274 My solution and answer: Let AC = be the sample points where King is not found AC = 51*51*51*51 or 51^4 = 6765201 Let A = be the total number of sample points A = 52*52*52*52 or 52^4 = 7311616 Pr(drawing at least one king) = 1 - Pr(drawing no king) = 1 - (51^4/52^4) = 1 - 0.9253 = 0.0747 Anyone can clarify? If my answer is correct, then the answer shown on the textbook could be a typo error. Otherwise, which part is my error. Thanks.
