1.If set A contains 5 elements, set B contains 8 elements and n(A B) = 3

then n(A U B) =

-

2.A = { a, b, c } and B = { 3, 6 }. Find the number of elements in A x B.

3.A = { 1, 2, 3, 4, 5 }, B = { 2, 4, 6 }.

What is ( B - A )?

4.If X = { odd numbers less than 11 } and Y = { even numbers less than 11 }, then ( A B ) = { whole numbers less than 11 }.

5.Given Y = { 0, 1, 2, 3, 4, 5 }.What is the cardinality of set Y?

6..If U = { first 5 letters in the english alphabet } and A = { vowels }, then A' = { b, c, d }.

7.If U = { 1 , 2, 3, 4, 5 } , A = { 1, 2, 3 }, B = { 2, 3 }, C = { 3, 4, 5 }, then ( ABC )' = { 3 }.

8.U = { factors of 12 }, A = { 1, 2, 3, 4 }, what is the A complement?

9.Given A = {0, 1, 2, 3, 4} and B = {0, 2, 4, 6, 8}, determine the cardinality of ( A U B ).

10.Given Y = { 0, 1, 2, 3, 4, 5 }. How many subsets does set Y have?
