Question
Using the sets $A, B, C,$ and $D,$ list the elements in each set. If the set is empty write $\varnothing$.$$\begin{array}{ll}A=\{1,2,3,4,5\} & B=\{4,5,6,7,8,9\} \\C=\{1,3,5,7\} & D=\{2,4,6,8\}\end{array}$$$$(B \cup C) \cap A$$
Step 1
The union of two sets is a set containing all elements that are in either set. So, we combine all the elements of B and C, but we only list duplicate elements once. So, $B \cup C = \{1,3,4,5,6,7,8,9\}$. Show more…
