Apologies I read your post too quickly  if you want the success faction
then see
http://www.boost.org/doc/libs/1_55_0/libs/math/doc/html/math_toolkit/dist_ref/dists/binomial_dist.html#math_toolkit.dist_ref.dists.binomial_dist.lower_bound_on_the_success_fract
and
www.boost.org/doc/libs/1_55_0/libs/math/doc/html/math_toolkit/dist_ref/dists/binomial_dist.html#math_toolkit.dist_ref.dists.binomial_dist.lower_bound_on_the_success_fract
Pay particular attention to the different methods used and the linked
references and discussions as some methods are particular adept at
returning "wrong" answers.
Hopefully I've answered the question you actually asked this time ;)
John.
