This is used to calculate coin toss probabilities.

 Enter probability of heads p = 0 < p < 1 Enter number of tosses n =

 b(k) = $$\binom{n}{k}p^k(1-p)^{n-k}$$ Binomial Distribution b() Normal approx:
 F(k) = $$\sum_{i=0}^{k}b(i)$$ Cumulative Distribution F() Normal approx:
 1 - F(k) = $$\sum_{i=k+1}^{n}b(i)$$ 1 - F() Normal approx:
