1.	The difference of {1, 2, 3} and {1, 2, 5} is the set ____________(a) {1}(b) {5}(c) {3}(d) {2}This question was posed to me during an interview.I'd like to ask this question from Set Operations in division Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» Correct choice is (c) {3} For explanation I would SAY: The DIFFERENCE of the SETS A and B DENOTED by A-B, is the set containing those elements that are in A not in B.
