1. In the following Venn Diagram, the region whose three components are marked with the letter x can be expressed as: (B-A) U (C-A). The expression is not unique. Find at least one different expression for this region. (4 points) X X X B 2. In the above diagram, if |A| =100, |B| =110, |C| = 120, IABI=20. JAN C| =25, IB n C| = 30, |A U BU C| =270, then |AnBn C| = ? (4 points). 1.
