Question

For problems 7-12, consider the sets below, and indicate if each statement is true or false. A = {1, 2, 3, 4, 5} B = {1, 3, 5} C = {4, 6} U = {numbers from 0 to 10} 7. 3 ∊ B 8. 5 ∊ C 9. B ⊂ A 10. C ⊂ A 11. C ⊂ B 12. C ⊂ U

Answer 1

Answer:

7.  True.  3 is in B = { 1, 3, 5 }.

8.  False.   5 is not in C = { 4, 6 }.

9.  True.   Each element in B = { 1, 3, 5 } is also in A = { 1, 2, 3, 4, 5 }.

10.  False.  6 is in C but 6 is not in A.

11.  False.  6 is in C but 6 is not in B.

12.  True.  Each element in C = { 4, 6 } is also in U = { numbers from 0 to 10 }.
