Answer:
The correct option is a.
Step-by-step explanation:
Given information:
Number of elements in set A = 4
Number of elements in set B = 3
We need to find n(A × B). It means we have to find the number of elements in set A × B.
If P and Q are two sets with elements m and n respectively, then the number of element in the set P × Q is m × n.



The value of n(A × B) is 12. Therefore the correct option is a.
 
        
             
        
        
        
The answer is 1,109,668 . 
here is why:
 18+ 1,500 is 1,518
1,518 + 150 is 1,668.
1,668+ 8,000 is 9,668
9,668 +  11,00,000 is 1,109,668 
18 ones is 18. 15 hundreds is 1,500. 15 tens is 150. 8 thousands is 8,000. 11 hundred thousands is 1,100,000.
        
                    
             
        
        
        
Need something to go off of and the choices.
