D Question 7 1 pts Caleb suggests an alternative proof to Claim 2.1.4: "Take A = {1, 2, 3, ... . 100}, B = {50, 51, 52, 53, ... , 200} and suppose that the universal set is N .Then (A U B) = ( 1, 2, 3, ... , 200}" = {201, 202, 203, ...} and An B = {101, 102, 103, ...} n {201, 202, 203 ...} = {201, 202, 203, ...}. We see that (A U B) = A n B', as needed." What is wrong with Caleb's solution?" O Caleb did not draw a Venn diagram. O Caleb computed the set An B" incorrectly. O To obtain a complete proof, Caleb should have done a few more examples. O Caleb computed the set (A U B) incorrectly. O Examples cannot be used to prove a general set identity
