Sup! Just a question for probability.
I have the answer, but I have no idea how to do the working out for it.
David chooses five cards from a normal pack of 52 playing cards.
a) How Many different selections are possible (no need to do this one, I get how to do this type of question.)
b) How many five-card hands will have exactly one ace?
c) How many five-card hands will have exactly two aces?
b and c are the ones I can't work out.
Many Thanks.
Correct me if I'm wrong, its been a while since general lol.
b) You know that there are four aces in a deck and the hand can only have one, which means after choosing your ace, there are 48 cards remaining. 4x48x47x46x45 should give you the answer.
c) 4x3x48x47x46.
That should be how its done (work these out and check the answers).
