Question

Set A is the set of factors of 12, set B is the set of even natural numbers less than 13, set C is the set of

odd natural numbers less than 13, and set D is the set of even natural numbers less than 7. The universal
set is the set of natural numbers less than 13.
What is An C?

Answer 1

Explanation:

Set A is the set of all factors of 12. Therefore,

Set A = 1,2,3,4,6,12

Set B is the set of even natural numbers less than 13. Even numbers are numbers that are divisible by 2 without a remainder. Therefore,

Set B = 2, 4, 6, 8, 10, 12

Set C is the set of odd natural numbers less than 13. Odd numbers

are not completely divisible by 2. They leave a remainder. Therefore,

Set C = 1, 3, 5, 7, 9, 11

Set D is the set of even natural numbers less than 7. Therefore,

Set D = 2, 4, 6

AnC means A intersection C. It means the elements that are common to set A and set C. Therefore,.

AnC = 1, 3
