1. The problem statement, all variables and given/known data A deck of cards is shuffled and the cards are turned up one at a time. What is the probability that all the aces will appear before any of the tens? 2. Relevant equations No equations that I know of are useful here... 3. The attempt at a solution This problem is one that deals without replacement due to the unspoken assumption. Ergo, the initial probability of drawing an ace off the top of the deck is 4/52. I am not sure where to go from here. I have a similar problem concerning drawing 10 cards and finding the probability of drawing five red cards without replacement. This example uses the binomial theorem, but I am having a hard time using that theorem here... Any helpful suggestions? Thanks for your time and help in advance! Much appreciated!
