Question

Given the following sets.

A = {0, 1, 2, 3}
B = {a, b, c, d}
C = {0, a, 2, b}

Find A C

{0, 1, 2, 3}
{a, b, c, d}
{0, a, 2, b}
empty set
{0, 2}

Answer 1

It looks like the ∩ sign may be missing from the question. If you mean to find A∩C, called the intersection, you're looking for elements that are both in A and C.

{0, 2} qualifies.

Answer 2

A∩C is:

{0,2}

Explanation:

We are given :

A = {0, 1, 2, 3}

C = {0, a, 2, b}

We have to find :

A∩C

A∩C= {0, 1, 2, 3} ∩ {0, a, 2, b}

={0,2}

(Since, intersection(∩) of two sets contains the points which are common in both the sets)

Hence, A∩C is:

{0,2}
