Question

based only on the venn - diagram shown and the proportion (not on any other knowledge you have) can you conclude that some people who are over 50 years old are not u.s. residents?
a. yes, because s and p do not intersect.
b. no, because there are parts of u in s and parts of s not in u.
c. no, because s and p do not intersect.
d. yes, because there are parts of p not in s and parts of s not in p.
e. yes, because s could also contain p.
f. no, because s could also contain p. but no, the two sets could be disjoint.

Explanation:

If two sets S (people over 50) and P (people with a certain condition) do not intersect, it means there are no elements that are in both sets. So we cannot conclude that some people who are over 50 years old are not in P (have the condition). When sets do not intersect, there is no overlap to make such a conclusion.

Answer:

C. No, because S and P do not intersect
