Let set a = {1, 3, 5, 7} and set b = {1, 2, 3, 4, 5, 6, 7, 8}

which notation shows the relationship between set a and set b?

Set A is a subset of set B. We can write it as  where the "C" looking symbol means "subset of"

All of the items found in set A can be found in set B. The other way is not true (eg: 8 in set B is not found in set A)

If you are drawing a venn diagram, all of circle A is inside circle B
