    Answer:
    M ∪ B = {-2, 1, 2, 3, 4, 5, 8}   Union of M and D
    M ∩ B = {1, 2, 3}    Intersection of M and D
    Step-by-step explanation:
    The union of two sets M and D is represented using the set notation M ∪ D and is the set of all elements that are in M or in D or in both. Since a set cannot contain duplicate elements we drop duplicates of elements
    So M ∪ B = {-2, 1, 2, 3, 4, 5, 8} where we drop repetitions of the elements 1, 2 and 3
    The intersection of two sets is the set of elements that appear in both sets ie the common elements
    So M ∩ B = {1, 2, 3}  since each of these elements appear in both sets
