The image above represents general binomial distribution. Four essential parameters are needed to calculate general binomial distribution: n, r, q, and q.
The formula for calculating general binomial distribution:
P(r successes) = n!⁄(n – r)!r!q(n – r)pr
Where;
P(r successes) = General Binomial Distribution
p = P(A)
q = P(not A)
Let’s solve an example;
Find the general binomial distribution when n is 8, r is 6, p is 1 and q is 0.
This implies that;
n = 8
r = 6
p = 1
q = 0
P(r successes) = n! ⁄ (n – r)!r!q(n – r)pr
P(6 successes) = 8! ⁄ (8 – 6)!6!(0)(8 – 6)(1)6
So, P(6 successes) = 8! ⁄ 2!6!(0)2(1)6
P(6 successes) = 40320 ⁄ (2)(720)(0)2(1)6
P(6 successes) = 40320 ⁄ 1440(0)2(1)6
Then, P(6 successes) = (28)(0)2(1)6
P(6 successes) = (28)(0)(1)
P(6 successes) = 0
Therefore, the general binomial distribution is 0.
