    Answer:  3/5

    ============================================================

    Explanation:

    The set {1, 2}U{2, 6, 7, 9}U{5, 6, 7} simplifies to {1,2,5,6,7,9} after we combine everything and sort the values. We toss any duplicates.

    Let B = {1,2,5,6,7,9}

    There are 6 items in set B out of 10 items in set A.

    The probability of landing in set B, if you pick something randomly from A, is 6/10 = 3/5
