Question

Given the following sets.
A = {0, 1, 2, 3}
B = {a, b, c, d}
C = {0, a, 2, b}

Find A∩B.
1 2 3 or 4

1 {0, 1, 2, 3}

2 {a, b, c, d}

3 {0, a, 2, b}

4 empty set {0, a}

Answer 1

$A=\{0,\ 1,\ 2,\ 3\}\\\\B=\{a,\ b,\ c,\ d\}\\\\A\ \cap\ B=\O\ (empty\ set)$

The intersection of A and B, denoted by A ∩ B, is the set of all things that are members of both A and B.
