Given a collection A, the complement of A is the collection of all facet in the global set U, yet not in A. We deserve to create Ac. You can also say match of A in U.Example #1.

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

Take a cshed look at the figure above. d and also f are in U, but they are not in A.As such Ac = d, fSometimes, rather of looking at a the Venn Diagrams, it may be simpler to create down the aspects of both setsThen, we show in bold the facets that are in U, however not in AA = a, b, cU = a, b, c, d
, fExample #2. Let B = 1 oarray, 1 pineapple, 1 banana, 1 apple Let U = 1 ovariety, 1 apricot, 1 pineapple, 1 banana, 1 mango, 1 apple, 1 kiwifruit Aacquire, we present in bold all elements in U, yet not in BBc = 1 apricot, 1 mango, 1 kiwifruitExample #3. Find the complement of B in UB = 1, 2, 4, 6 U = 1, 2, 4, 6, 7, 8, 9 Complement of B in U = 7, 8, 9Example #4. Find the match of A in U A = x / x is a number bigger than 4 and also smaller than 8 U = x / x is a positive 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 below mirrors the shaded area for the complement of set A
