Question

Five cards are dealt from a deck of 24 cards to form a euchre hand. Is this a combination or permutation?

4 actors are chosen To play the Beatles in a film.
Is this combination or permutation?

Answer 1

for the cards, does the way you arrange your cards make any difference? If not, it's a combination.

For the actors, of course it makes a difference who plays which part. So, a permutation. But, if you just want to get four guys, it's a combination.
