4, one in each suit (Hearts, Diamonds, Spades, Clubs.)
In a standard deck of 52 playing cards, there are two black tens: the Ten of Spades and the Ten of Clubs. Each suit contains one ten, and since Spades and Clubs are the black suits, these are the only black tens in the deck.
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

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%.
