I'm having a little difficulty on this problem:
"In advertising a beach condo near Destin, Florida, a property owner can specify (1) whether or not pets are allowed, (2) whether the rent is based on off-season, during summer season, or during spring break, (3) whether or not children under 12 are allowed, (4) whether the minimum stay is 4, 7, or 10 days, and (5) whether or not is beach front. How many different versions of the ad can be generated?"
I thought version was just another word for combination, but if that is the case how do I figure out which would be n and which would be r for the equation :
(n r) n!/r!(n-r)!
