Question 1154143: Calculate the number of distinct subsets and the number of distinct proper subsets
{x|x is a day of the week}
Thank you in advance,
SYL Answer by ikleyn(52778) (Show Source):
The set contains 7 elements (Mon-Fri, Sat and Sun).
Every finite set containing "n" elements, has N = subsets, including the empty set and improper set.
In your case, n= 7 and N = = 128 subsets, including the empty set and improper set.
ANSWER. = 128 subsets, in all; and 128-1 = 127 proper subsets.

Dear visitor SYL !
If I remember correctly, I just solved very similar problem (TWIN problem) for you with full explanation several days ago.
