If R is to be transitive, ( 1) requires that 1, 2 be in R, ( 2) requires that 2, 2 be in R, and ( 3) requires that 3, 2 be in R. And since all of these required pairs are in R, R is indeed transitive. WebThis problem has been solved!

No. Counterexample: A = {1, 2, 3} and R1 = { (1,2), (2,3), (1, 3)} and R2 = { (1, 3)}. R1 is transitive and R2 is transitive (vacuously). Then, R1\R2 = { (1,2), (2,3)}. Therefore, R1\R2 is not transitive because it does not include (1, 3). Oct 12, 2011 #10 micromass Staff Emeritus seeking good eats taco stuffed peppers
