Answer: [tex]B \cup C = \{a, l, g, e, b, r, m,y,t,h\}[/tex]
The U symbol between B and C means "set union". A set union is where we throw all the elements of both sets into one big set. Toss out any duplicates that show up. In this case, there are no common elements so there are no duplicates. The order of the items in any set does not matter.
