Question

A={1,4,5,8) B = { 2, 8, 9) C = {3,5,8) Be (C-A) = { Ex: 3,6 }

Answer 1

The set (C-A) is {3, 6}.

To obtain this set, we first subtract the elements in A from the elements in C, which gives us {3, 0, 3}. Then, we remove any duplicates and sort the remaining elements in ascending order to get {3, 6}.
