Question

If A = {1, 2, 3, 4, 5, 6}, B = {1, 2, 3, 5, 7, 9} and C = {3, 5, 6, 7, 8, 9}, What is the intersection of the set A and set C? {1, 2, 3, 4, 5, 6, 7, 8, 9} {1, 2, 3, 4, 5, 6, 7, 8, 9} {1, 2, 3, 4, 5, 6, 7, 9} {1, 2, 3, 4, 5, 6, 7, 9} {3, 5, 6} {3, 5, 6} {1, 2, 3, 5}

Answer 1

`A\,\cap\,C = \{3,5,6\}`

Explanation:

From Set Theory we know that intersection is a binary operation between two sets consisting in labeling the common elements of both sets. If
`A=\{1,2,3,4,5,6\}` and
`C =\{3,5,6,7,8,9\}`, then
`A\,\cap\,C = \{3,5,6\}`.
