Question

Let A = (1,3,4,6,8) B=(2.3.4.5.7)C= (1.2.6.9, 10) Find (a) A/B (B)B/A (C) A/C (D) C/A​

Answer 1

(a) A/B refers to the set of elements that are in A but not in B. So, A/B = {1, 6, 8}

(b) B/A refers to the set of elements that are in B but not in A. So, B/A = {2, 5, 7}

(c) A/C refers to the set of elements that are in A but not in C. So, A/C = {3, 4, 8}

(d) C/A refers to the set of elements that are in C but not in A. So, C/A = {2, 9, 10}

Note: It's important to clarify what the "/" symbol means in set theory, which is the set difference operator. It represents the elements that are in the first set but not in the second set.
