If A = {1, 3, 7, 11, 14, 19), B = {2, 3, 5, 7, 11, 17, 19), C = {3, 6, 9, 12, 15)

Determine the following:
1. A-B = { }
2. B - C = { }
3. A- C = { }
4. C-B = {
5. B - A = { }​

Answer:

1.A-B={1,14}

2.B-C={2,5,7,11,17,19}

3.A-C={1,7,11,14,19}

4.C-B={6,9,12,15}

5.B-A={2,5,17,19}

Step-by-step explanation:

we just subtract or cancel the element that the same and then we will get the remaining elements of the first set.

for example: A={1,2,3};B={3,4}

we will cancel 3 in the set A because 3 is the element of set B and since 4 is not an element of set A we don't need to cancel that.The remaining element of set A={1,2}
