Question 1018649
.
How many subsets are there for the set {1,3,5,7,9,11}?
--------------------------------------------------------


Your set consists of 6 elements.


So, the number of all its subsets is {{{2^6}}} = 64, including the empty subset and the subset consisting of all 6 elements.


If you'd like to constrain yourself by only "proper" subsets, their number is {{{2^6}}} - 2 = 64 - 2 = 62.
