Do not round your intermediate computations, and round your answer to three decimal places. Answer by ikleyn(52925) (Show Source):

~~~~~~~~~~~~~~~~~~~
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
