A stack of 8 different cards are shuffled and spread out face down. if 5 cards are turned face up, how many different 5-card com
binations are possible?
1 answer:
There are 56 different combinations of cards.
This is a combination problem, not a permutation.
Therefore, first we need to find the number of total possibilities.
It would be: 8 x 7 x 6 x 5 x 4
6720
Then, we need to divide those possibilities by the number those 5 cards can be rearranged.
6720 / (5 x 4 x 3 x 2 x 1) = 56
