Question
Using the sets $A, B, C,$ and $D,$ list the elements in each set. If the set is empty write $\varnothing$.$$\begin{array}{ll}A=\{1,2,3,4,5\} & B=\{4,5,6,7,8,9\} \\C=\{1,3,5,7\} & D=\{2,4,6,8\}\end{array}$$$$A \cup B$$
Step 1
Step 1: The union of two sets, denoted by $A \cup B$, is the set of elements which are in $A$, in $B$, or in both $A$ and $B$. Show more…
