A) 128
B) 216
C) 240
D) 160
Correct Answer: D
Solution :
\[n\,(C)=224,\,n\,(H)=240,n\,(B)=336\] \[n\,(H\cap B)=64,\,\,n(B\cap C)=80\] \[n(H\cap C)=40\], \[n(C\cap H\cap B)=24\] \[n\,({{C}^{c}}\cap {{H}^{c}}\cap {{B}^{C}})=n\,[{{(C\cup H\cup B)}^{c}}]\] \[=n(\cup )-n(C\cup H\cup B)\] \[=800-[n(C)+n(H)+n(B)-n(H\cap C)\] \[-n(H\cap B)-n(C\cap B)+n(C\cap H\cap B)]\] \[=800-[224+240+336-64-80-40+24]\] \[=800-640=160\].You need to login to perform this action.
