Question
If A = {1, 2, 3, 4, 5, 6}, B = {2, 4, 6, 8}. Then A – B is:
- {1, 3, 5}
- {2, 4, 6, 8}
- {1, 2, 3, 4, 5, 6}
- None of these
Solution
The operation A - B is also known as the difference of sets. It results in a set that includes elements that are in set A but not in set B.
Given A = {1, 2, 3, 4, 5, 6} and B = {2, 4, 6, 8}, we can see that the elements 2, 4, and 6 are common to both sets.
So, when we subtract set B from set A, we remove the elements that are common to both sets from set A.
Therefore, A - B = {1, 3, 5}.
So, the correct answer is {1, 3, 5}.
