    Answer:

    0.3935 to 4 places of decimals.

    Step-by-step explanation:

    Use  binomial probability tables  or an online probability calculator.

    Here Prob(a singles success) = 0.08333  ( that is 1/12)

    Number of successes = 3 and number of trials = 27.

    You want the probability of the variable X being >= x.
