A blackjack hand consists of 2 cards drawn from a 52-card deck. The order in which the cards are drawn does not matter.
(a) How many different blackjack hands are there?
(b) In blackjack, the suit of the card is irrelevant to the game. If we do not make a distinction between the different suits, now how many different blackjack hands are there?
(c) In blackjack, 10s, Jacks, Queens, and Kings are all worth 10 points and thus have an identical function in the game. If we do not make a distinction between 10s, Jacks, Queens, and Kings, nor between the different suits, now how many blackjack hands are there?
