SETS

It is an operation on sets that contains elements that are common to both sets.

• Complement of a Set

• Difference of Two Sets

• Intersection of Sets

• Union Sets

Given the sets
A = {2, 4, 6, 8} and B = {3, 4, 5, 6, 7}

What is  $A\ -\ B$  ?

• {2, 3, 4, 5, 6, 7, 8}

• {4, 6}

• {8}

• {3, 5, 7}

Given the sets
A = {a, b, c, d, e} and B = {a, c, d, f}

What is  $A\ \cap\ B$  ?

• {a, c, d}

• {a, b, c,d e, f}

• {b, e}

• {f}

Given the sets
A = {2, 3, 4, 5} and B = {2, 4, 5, 6}

What is  $A\cup B$  ?

• {2, 4, 5}

• {2, 3, 4, 5, 6}

• {3}

• {6}

What is intersection of A and B?

• A ∪ B
