I know what to do but, is B the right answer

anonymous · Answer

@aum you still there or what?

aum · Answer

The numbers in each cube go from 1 to 6.
When the numbers are added, the lowest sum will be 2 and the highest sum will be 12.
Sum = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
A = {3, 5, 7, 9, 11}
Sum of number cubes divisible by 4 are: 4, 8, 12.  
So B = {4, 8, 12}

What is A U B ?

A = {3, 5, 7, 9, 11}
B = {4, 8, 12} 
A union B = {3, 4, 5, 7, 8, 9, 11, 12}
