Given: U = {Even numbers between 0 and 30} P = {Multiples of 6 between 0 and 30} Q = {Multiples of 4 between 0 and 30} Find (P∪Q)c

A.

{2, 10, 14, 22, 26}

B.

{0, 10, 14, 22, 26}

C.

{2,4, 14, 18, 26}

D.

{0, 2, 6, 22, 26}

Correct Answer: {2, 10, 14, 22, 26}

Explanation

U = {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30} P = {6,12,18,24,30} Q = {4,8,12,16,20,24,28} P∪Q = {4,6,8,12,16,18,20,24,28,30} (P∪Q)c = {2,10,14,22,26}

U = {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30} P = {6,12,18,24,30} Q = {4,8,12,16,20,24,28} P∪Q = {4,6,8,12,16,18,20,24,28,30} (P∪Q)c = {2,10,14,22,26}
