Binomial Distribution Calculator
This is used to calculate coin toss probabilities.
Enter probability of heads
p
=
0 < p < 1
Enter number of tosses
n
=
Probability of exactly k heads
b(k)
=
\(\binom{n}{k}p^k(1-p)^{n-k}\)
Binomial Distribution
b(
)
Normal approx:
Probability of k or less heads
F(k)
=
\(\sum_{i=0}^{k}b(i)\)
Cumulative Distribution
F(
)
Normal approx:
Probability of more than k heads
1 - F(k)
=
\(\sum_{i=k+1}^{n}b(i)\)
1 - F(
)
Normal approx:
