Question

If A = {set of th first four natural numbers} and B = {set of the first four whole numbers}, then sets A and B are _______.

• A. Equal sets.
• B. Infinite sets.
• C. Null sets.
• D. Equivalents sets.

Answer 1

The correct option is D

Equivalents sets.

Given,

A = {First four natural numbers} and B = {First four whole numbers}

A = { 1, 2, 3, 4} and B = {0, 1, 2, 3}

n(A) = 4 and n(B) = 4

Number of elements of set A and set B are equal.

$\Rightarrow$ Set A and Set B are equivalents sets.
