2 black tens in a deck of cards.
A standard 52 cards deck contains 4 kings and 4 tens. Given that the type of the card does not matter, we have a total of 8 valid cards (4 kings + 4 tens) to choose from a 52 cards deck. Hence the probability is 8/52.
The probability of drawing two jacks and three tens of any suite from a standard deck of cards is: 5C2 ∙ (4/52)∙(3/51)∙(4/50)∙(3/49)∙(2/48) = 0.00000923446... ≈ 0.0009234% where 5C2 = 5!/[(5-2)!∙(2!)] = 10

2 black tens in a deck of cards.
There are 4 aces and 16 tens (including face cards) in a standard 52-card deck of cards, so there are 64 different blackjack combinations. There are 52!/(50!2!) = 1326 different two-card combinations in the deck, so the odds are 64/1326 = 0.048, or slightly less than 5%.
