A) 6
B) 8
C) 10
D) 12
Correct Answer: B
Solution :
[b] We have \[A=\{0,1,2\}\] \[B=\{2,3\}\] \[C=\{3,4\}\] \[A\cup B=\{0,1,2,3\}\] \[(A\cup B)\times C=\{(0,3),(0,4),(1,3);(1,4);(2,3),(2,4),(3,3);(3,4)\}\]\[\therefore \,\,\,n\left[ (A\cup B)\times C \right]=8\]You need to login to perform this action.
