1) In this problem, the set A is IRRELEVANT and the info about it is irrelevant, too. 2) The set (B U C) is the union of the sets B and C. So, (B U C) consists of elements that belong to B or C. Therefore, list all elements that belong to B or to C, and take care that elements do not appear in the list more than once. Having these instructions is enough for you to complete the assignment on your own.
