Question 1182066: A binomial experiment with probability of success p=0.73 and n=9 trials is conducted. What is the probability that the experiment results in more than 7 successes?
Do not round your intermediate computations, and round your answer to three decimal places.

It is a binomial distribution probability problem.

    - number of trials         n =   9 ;
    - number of success trials k >   7;
    - Probability of success on a single trial p = 0.73.



We need calculate  P(n=9; k>7; p=0.73).      


To facilitate calculations, I use an appropriate online (free of charge) calculator at this web-site

It provides nice instructions  and  a convenient input and output for all relevant options/cases.


    P(n=9; k > 7; p=0.73) = 0.25484138904,   or   0.2548 (rounded).       ANSWER

Solved.
