The probability that the second card is a 10 point card is 16/51. So the probability of an ace first blackjack is (4/52). (16/51). Multiply this by 2 because the ten could just as easily be the first card and the answer is 2. (4/52). (16/51) = 128/2652 = 0.0482655, or about 1 in 20.7.

The value of a hand is the sum of the point values of the individual cards. Except, a 'blackjack' is the highest hand, consisting of an ace and any 10-point card, and it outranks all other 21-point hands.
As the dealer, the basic rules of blackjack still apply. Cards 2 through 10 are worth their face value. The jack, queen and king are worth 10 points each. The ace has a value of either 1 point or 11 points, depending on its usage in your hand.
