If A= {-2,-1,0,3}, B= {-2,3,7}. Find (A-B).
Question
If A= {-2,-1,0,3}, B= {-2,3,7}. Find (A-B).
Solution
The difference of two sets, A - B, is the set of all elements that are in A but not in B.
Step 1: Identify the elements in set A, which are -2, -1, 0, 3.
Step 2: Identify the elements in set B, which are -2, 3, 7.
Step 3: Determine which elements are in A but not in B.
From the given sets, the elements -1 and 0 are in A but not in B.
So, A - B = {-1, 0}.
