Here's something I know there must be a way to easily figure out... but not by me!
THE QUESTION...
if I have x number of categories to choose from, how many combinations can I get?
for example I think that if I had 4 categories there are 15 possible combinations
categories A, B, C, D
combinations:
A
B
C
D
AB
AC
AD
ABC
ABCD
BC
BCD
CD
ACD
ABD
BD
Am I missing any?
so if 4 yeilds 15
5 yields ?
6 yields ?
I'm know a pattern develops but how does it work? Sorry I've been out of school for so long and I don't know where to begin.
