Let u be the set contains all the twelve months in the year, that is, u = {jan. , feb. , mar. , · · · , nov. , dec.}. given that a = {jan. , feb. , mar. , apr. , may} and b = {apr. , may , june , july , aug. , sep. , oct.}. find (a) a\b (b) b\a (c) a ∩ b (d) a ∪ b (e) ac ∩ bc (f) ac ∪ bc (g) (a ∩ b) c (h) (a ∪ b) c (i) is the statement “ (a ∪ b) c = ac ∪ bc ” true? verify it. (j) is the statement “ (a ∩ b) c = ac ∪ bc ” true? verify it.
