    Set Operations: C U U' - Solving with a Simple Subset of the Universal Set

    some help on sets! can anyone tell me the answer to this?? if U (universal set) = {1,2,3,4,5,6,7,8,9,10,11,12,13,14} C (just a simple subset of the universal set U)= {1,2,3,4,5} then what would be the answer if: C U U' ? (subset C union universal set complement) thanks!
