Given a collection A, the enhance of A is the collection of all element in the universal collection U, yet not in A. We have the right to write Ac. Friend can additionally say complement of A in U.Example #1.

You are watching: The complement of "at least one" is

Take a close look at the number above. D and f room in U, but they room not in A.Therefore Ac = d, fSometimes, instead of looking in ~ a the Venn Diagrams, it might be less complicated to write down the aspects of both setsThen, we show in bolder the facets that room in U, yet not in AA = a, b, cU = a, b, c, d
, fExample #2. Let B = 1 orange, 1 pineapple, 1 banana, 1 apple let U = 1 orange, 1 apricot, 1 pineapple, 1 banana, 1 mango, 1 apple, 1 kiwifruit Again, we present in interlocutor all aspects in U, yet not in BBc = 1 apricot, 1 mango, 1 kiwifruitExample #3. Find the enhance of B in UB = 1, 2, 4, 6 U = 1, 2, 4, 6, 7, 8, 9 Complement the B in U = 7, 8, 9Example #4. uncover the complement of A in U A = x / x is a number bigger than 4 and smaller than 8 U = x / x is a hopeful number smaller than 7 A = 5, 6, 7 and U = 1, 2, 3, 4, 5, 6Ac = 1, 2, 3, 4 Or Ac = x / x is a number bigger than 1 and also smaller than 5 The graph listed below shows the shaded an ar for the enhance of collection A
