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)....

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
