Since there are only 4 tens in a deck of cards, there is only one way. However, if the order by which they are drawn matters, there are 24 ways:10H, 10C, 10S, 10D10H, 10C, 10D, 10S10H, 10D, 10C, 10S10H, 10D, 10S, 10C10H, 10S, 10C, 10D10H, 10S, 10D, 10CNote there are 6 combinations where the 10 of Hearts is drawn first. It stands to reason therefore, that there will also be 6 when the 10 of Clubs is drawn first, another 6 for the 10 of Diamonds first and finally another 6 when the 10 of Spades is drawn first. Since 4 lots of 6 combinations is 24, there are 24 total combinations.Mathematically, that can be calculated without the example set, such that 4 factorial (4! Or 4 x 3 x 2 x 1) is the full set of combinations. For example, there are 4 suits to make the first draw from, and therefore 4 possibilities. Once one has been picked, there are 3 possibilities for the second card chosen. So far there are 12 different ways of making the first two picks. Once the second draw is made, there are 2 possible cards left to chose from. And finally, once that pick is made, the final card is the only one that is left.
