Question 789220: I own 7 suits and 9 ties. I want to take 4 suits and 3 ties on a trip.
how many different ways can I choose 4 suits to pack?
is this a permutation question (permutation of 4 out of 7) or a combination question?
thanks so much!!! Answer by xinxin(76) (Show Source):
You can put this solution on YOUR website! It is a combination question because choosing suits 1,2,3,4 is the same as choosing suits 2,1,3,4.
Use combination formula.
