Answer 2

Step-by-step explanation:

Given:

$A=$ {$1,3,5,7$} $,$ $B=$ {$2,4,6,8$}

To find:

$A$ ∪ $B$

Solution:

$A$ union $B$ formula is,

$A$ ∪ $B$ $=$ {$X:X$ ∈ $A$ $(or)$ $X$ ∈ $B$}

By using the $A$ union $B$ formula, we find writing all elements of $A$ and $B$ in one set by avoiding duplicates.

So, $A$ ∪ $B$ $=$ {$1,3,5,7$} ∪ {$2,4,6,8$}

Here, the element in the answer set do need to be in order.

$A$ ∪ $B$ $=$  {$1,2,3,4,5,6,7,8$}

Hence the answer is $A$∪$B$ $=$ {$1,2,3,4,5,6,7,8$}.
