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

Question

Given the following sets.

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

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

 

Find A ( Its a U but upside down) B.

 

these are the choices im so confused

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

 

Answer 1

That would be A∩B (intersection of sets A and B).

 

A={0,1,2,3}

 

B={a,b,c,d}

 

A and B have nothing in common, so A∩B = empty set

Answer 2

the question is to find the intersection set of A and B.

 

it is empty
