EXAMPLE OF QUESTION~~

Let M = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}. A = {2,4,7,10,13,15},  B = {3,4,7,10,15}, C = {3,4,8,14} and D = {3,4,7,9} Determine :

i) A Ụ B        ii) A ∩ D      iii) (A Ụ B) ∩ C     iv) B /C     v) B + C


Answer:


i) A Ụ B = {2,3,4,7,10,13,15}
ii) A ∩ D = {7}
iii) (A Ụ B) ∩ C = {3,4}
iv) B /C = {2}
v) B + C = {4,5,7,9,10,15)
