Answer:

We will typically use upper case letters for the names of sets.

Let

A = {a, b, c, d, e, f}

B = {4, 9, 2, 7}

C = {Larry, Moe, Curly}

D = {cat, dog}

N = {1, 2, 3, 4, 5, 6, 7, ...}

F = {the people in this room}

Step-by-step explanation:

Two sets are said to be equal if they contain exactly the same elements.

Examples

{a, b, c} = {b, c, a}

{4, 2, 7, 9} = B

On the other hand:b9
