Question 259057: What is the number of subsets of set B = {3, 6, 9, 12, 15, 18}?
Answer by drk(1908)   (Show Source):
You can put this solution on YOUR website! There are 2^6 or 64 subsets.
rather than go through all of them, I will give you the pattern:
subsets of {3} - -> {empty}, {3} - -> 2
subsets of {3,6} - -> {empty}, {3}, {6}, {3,6} - - > 4
1 term got 2
2 terms got 4
this is 2^terms
