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.
