Question
Using the sets $D . E,$ and $F$ list the elements in each set. If the set is empty write $\varnothing .$ $$D=\{3,5,7\} \quad E=\{2,4,6,8\} \quad F=\{1,2,3,4,5\}$$$$(D \cup F) \cap E$$
Step 1
The union of two sets is the set of all objects that are a member of $D$, or $F$, or both. So, we combine all the elements from both sets, but we only list each element once, even if it is in both sets. So, $D \cup F = \{1,2,3,4,5,7\}$. Show more…
