How many proper and improper subsets are there in the set K = { a, b, c, d, e}?
A
10
B
25
C
32
D
50
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
For a set with n elements, the total number of subsets is given by:
2\(^n\)
where n = the number of members of the set = 5
so, 2\(^5\) = 32
(every set is an improper subset of itself)
