Question

subset of first five odd numbers pls help me​

Answer 1

Answer:

First 5 odd numbers are 1,3,5,7 and 9

Let the set be A

A= {1,3,5,7,9}

Subsets of A are { ( ), (1), (3), (5), (7), (9), (1,3), (1,7), (1,9), (1,5), (3,5), (3,7), (3,9), (5,7), (5,9), (7,9), (1,3,5), (1,3,7), (1,3,9), (1,5,7), (1,5,9), (1,7,9), (3,5,7), (3,7,9), (3,5,9), (1,3,5,7), (1,3,5,9), (1,5,7,9), (3,5,7,9), (1,3,5,7,9),.. and 2 more subsets

No. of subsets = 2^n ,where n is no. of elements in the set

So the answer is 2^5 = 32

Hope it helps
