Operations with sets The  union  of two sets is a set containing all the numbers in those sets, but any duplicates are only  written once. The symbol for finding the union of two sets is  Example 1 Find the union {1,2,3}   {3,4,5}. {1,2,3}   {3,4,5} = {1,2,3,4,5} The union of the set with members 1, 2, 3 together with the set with members 3, 4, 5 is the set with  members 1, 2, 3, 4, 5. The  intersection  of two sets is a set containing only the members that are in each set at the same

Unformatted text preview: time. The symbol for finding the intersection of two sets is . Example 2 Find the intersection {1,2,3} {3,4,5}. {1,2,3} {3,4,5} = {3} The intersection of the set with members 1, 2, 3 together with the set with members 3, 4, 5 is the set that has only the 3. If you were to let the set with {1,2,3} be set A , and the set with {3,4,5} be set B , then you could use Venn diagrams to illustrate the situation (see Figure 2)....
