Answer:
i. A - B = {a,c,}
ii. B - A ={b,d}
iii. The operation is not commutative.
Step-by-step explanation:
i. A - B = {a,c,} is the set of elements in A but not in B.
ii. B - A ={b,d} is the set of elements in B but not in A.
iii. Since A - B is not equal to B - A then the operation is not commutative.
