In case of Set C the possible set is {2,4,6,....98} and in case of Set D, the possible set is given by { 10, 20, 30,...150}. Now C ∩ D means the set that is common to both C and D. Let's name the set as E. Hence Set E will have {10,20,30,40,50,60,70,80,90} Hence there are 9 observations which are common to both Set C and Set D.
