Five cards are drawn from a standard deck of cards.

a). how many groups of cards are possible?
b). how many groups would have 4 of a kind?

can you solve this in combinations (from probability unit, counting techniques) !

If all the cards are of the same suit, then since there are four suits in a deck, then the number is  4 x  13C4  = 4 x ( 13 x 12 x 11 x 10 ) / ( 4! )  = 2860.

If the cards are to be of different suits ,then the number of combinations would be

13 x 13  x 13 x 13 = 28561

4x and 6y

im not sure though

77
