I have a question about binomial distribution(adsbygoogle = window.adsbygoogle || []).push({});

There is a random var X follows Binomial distribution ~B(n,p), where n is known but p is UNKNOWN.

It is also known that a for known value of x, CDF(x) = Pr(X<=x) = 0.9

Is there anyway to estimate p?

To give a concrete example, if n=8, CDF(5) = 0.9, can I find p?
