Hi If you are dealt 4 cards from a shuffled deck of 52 cards find the probability that all 4 cards are queens. Dealt 4 52C4 is the total ways to be dealt 4 cards nCr = (n!)/(r!(n - r)!) Using nCr calculator button: 52C4 = 270,725 ways to be dealt 4 cards P = Particulars / all Possible ways (only 1 way of drawing 4 Queens) P(4 Queens)= 1/270,725 = .0000037 Not Likely! Wish You the Best in your Studies.
