c) Null Set
Work Step by Step
a) This question is asking for numbers in set A OR set B. These numbers are 1,2,3,4,6,8.
b) This question is asking for numbers in set B AND set C. No numbers exist, so the answer to this question is the null set.
c) This question is asking for numbers in the set for the answer to part a and numbers in the sets to the answer to part b to this question. Since there are no numbers in answer B, the answer to this question is the null set as well.
