Given the sets A={2,15,21,5,13} and B={6,9,15,12,21} , what is the sum of all the elements in A�¾B ?
To find the sum of all the elements in A�¾B (the union of sets A and B), you first need to combine both sets into one set, removing any duplicate elements.
Here are the steps to find the sum:
Step 1: Combine the sets A and B to get the union A�¾B: A�¾B = {2, 15, 21, 5, 13, 6, 9, 12}.
Step 2: Add up all the elements in the set A�¾B: 2 + 15 + 21 + 5 + 13 + 6 + 9 + 12 = 83.
Therefore, the sum of all the elements in A�¾B is 83.
