Question

Which of the following pair of sets are equal sets?

$X=\left\{0,1,2,3\right\}$

$Y=\left\{Wholenumberlessthan4\right\}$

Answer 1

Two sets are said to be equal, if they contains exactly same element.

Given pair of set:

$X=\left\{0,1,2,3\right\}$ and $Y=\left\{Wholenumberlessthan4\right\}$

As we know in set order of element does not matter.

The listed elements of set $Y$ can be written as $Y=\left\{0,1,2,3\right\}$

Both sets $X=\left\{0,1,2,3\right\}$ and $Y=\left\{0,1,2,3\right\}$ contains exactly same number of elements.

Hence, the given pair of sets $X=\left\{0,1,2,3\right\}$ and $Y=\left\{Wholenumberlessthan4\right\}$ are equal sets.
