Let P(x, y): 2x + y = 1, where the universe of discourse is the set of all integers. Examine the truth values of the following: (c) (i) VxayP(x,y) (ii) VVYP(x,y) At the end of each year, students at EZ School received ribbons at a school- wide awards ceremony. This year, 120 students receive gold stars for perfect attendance, 180 receive certificates for participating in the science fair and 80 students receive blue ribbons for outstanding grades. Of these, 40 students who receive the attendance star receive no other award, 50 students who receive the science fair certificate receive no other award, and 10 students receive the blue ribbon receive no other award. In addition, 10 students receive all three awards (d) and 65 students receive no awards. (i) Illustrate this situation by a Venn diagram. (ii) Compute how many students attend the school this year.
