Explanation / Answer
Your answer of 400 outfits is correct. Your answer of 65780 combinations is correct. Probability of being dealt a flush is incorrect. You have to choose only one suit, and then 5 cards from that suit.So, (4C1) (13C5) = # (I don't have a calculator in front of me so youcan calculate it) Then take that and divide by 65780 like you did in thebeginning. I hope that helps!
