Question

how many subsets doers the set containing 10 elements have

Answer 1

out of these 1024 subsets, one subset is the null set so, the number of non-empty subsets of the set containing 10 element is 1024-1=1023

Answer 2

Answer:

It's based upon basic concept of Combinations.

Since there are 10 elements, every element has 2 choice:-

1. To be in the sunset

2. Not in the subset.

So, we get Total No. of Subsets = 2× 2 × 2…..ten times = 2^(10) = 1024
