A fruit company guarantees that 89% of the pineapples shipped will ripen within 4 days
of delivery. Find the probability that at least 10 pineapples in a case of 12 are ripe within 4 days.
~~~~~~~~~~~~~~~~~~~~~~~~~~

It is a Binomial experiment with the number of trials n= 12 and the probability
of the individual success of p= 0.89 for each individual trial.


    P(at least 10 successes of 12 trials) = P(10) + P(11) + P(12) = use the standard formulas for binomial distribution = 

    =  = 

    =  = 0.8623  (rounded).    ANSWER

Solved.
