(P = {1, 3, 5, 7, 9}, Q = {2, 4, 6, 8, 10, 12}, R = {2, 3, 5, 7, 11}) are subsets of (U = {1, 2, 3, … , 12}). Which of the following statements is true?
-
A.
(Q cap R = varnothing) -
B.
(R subset P) -
C.
((R cap P) subset (R cap U)) -
D.
(n(P’ cap R) = 2)
Correct Answer: Option C
Explanation
All the statements are false except option C.
(R cap P = {3, 5, 7} and R cap U = {2, 3, 5, 7, 11})
(therefore (R cap P) subset (R cap U))
