Find the difference of the sets A = {1, 2, 3, 4, 5} and B = {3, 4, 5, 6, 7}.
Question
Find the difference of the sets A = {1, 2, 3, 4, 5} and B = {3, 4, 5, 6, 7}.
Solution
The difference of two sets A and B, denoted by A - B, is the set of elements which are only in A but not in B.
So, for the sets A = {1, 2, 3, 4, 5} and B = {3, 4, 5, 6, 7}, the difference A - B would be calculated as follows:
- Identify the elements in set A that are not in set B. These elements are {1, 2}.
- Therefore, the difference of the sets A and B, A - B = {1, 2}.
