    Unhappy Binomial distribution

    I have tis questions, I'd appreciate help.

    X follows a binomial distribution with n=15 and p=0.19 (answer to four decimal places not two percentage decimal points.

    1. P(x=3)= I got 0.2097

    2. P(x>=3)= Dont know how to do it.

    Thanks,

    Mauricio

    All you need to sum 3 terms not 13.
