Venn Diagrams : Union and Intersection of Sets

Given the universal set of {x 0<x< 10}(this should read less than and equal too) and sets A,B,and C as defined below:
A={factors of 6)
B= {factors of 10}
C= {odd numbers}

a. List the elements in A U B U C. (they are suppossed to be upside down U"s )

b. State A U (B U C). (the U in between the b, c is the wrong way).

c. State n(A U C) and describe the set in words. (once again the U is the wrong way!!!).

We can find that

a) then the intersection A^B^C = (1) ...

Solution Summary

Union and intersection operations are performed on three sets.
