Instead of doing this routine calculations for you,  I will refer to the lessons

    - Simple and simplest probability problems on Binomial distribution
    - Typical binomial distribution probability problems
    - How to calculate Binomial probabilities with Technology (using MS Excel)
    - Solving problems on Binomial distribution with Technology (using MS Excel)
    - Solving problems on Binomial distribution with Technology (using online solver)

in this site.

You will find there many similar typical problems of this class,  solved and explained with all details.

So,  learning from these lessons,  you will be able to solve such problems on your own, which is your
PRIMARY  MAJOR  GOAL  visiting this forum  (I believe).
