Question

How many different subsets of the set {10, 14, 17, 24} are there that contain an odd number of elements?

• A. 8
• B. 6
• C. 3
• D. 10

Answer 1

The Correct Option is A

Choosing 1 or 3 from the 4 values will make a subset that contains an odd number.
so choose 1 out of 4 is 4c1 = 4
and choose 3 out of 4 is 4c3 = 4
total = 4+4 = 8
The correct option is (A): 8
