Cumulative distribution function: Difference between revisions

: <math>F(k;n,p)=\Pr(X\leq k)=\sum _{i=0}^{\lfloor k\rfloor }{n \choose i}p^{i}(1-p)^{n-i}</math>
 
Here <math>p</math> is the probability of success and the function denotes the discrete probability distribution of the number of successes in a sequence of <math>n</math> independent experiments, and <math>\lfloor k\rfloor\,</math> is the "floor" under <math>k</math>, i.e. the [[greatest integer]] less than or equal to <math>k</math>.
