    Answer:

    42

    Step-by-step explanation:

    Given that:

    Sample space = {1, 2, 3, 4, 5,6}

    Probability of obtaining an odd number in a single roll :

    Probability = required outcome / Total possible outcomes

    Required outcome = {1,3,5} = 3

    Total possible outcomes = 6

    P(odd number) = 3/6 = 1/2

    Number of odds on 84 die rolls :

    1/2 * 84 = 42 times
