How do you solve this problem? What is the probability that you are not dealt a 10?

Answer 1

More information is needed. Do you mean a single card from a deck of 52? Then it's 4/52 = 1/13.

Do you mean card valued at 10 in the game of blackjack? Then it could be a 10 or a face card, 16/52 = 4/13 (assuming a single deck in the shoe).

Or do you mean a tarot deck? We once played poker with a tarot deck. I got a full house and three people died (rim shot).
