### ⟩ What is binomial probability formula?

P(x)= p x q n-x n!/[(n-x)!x!]

where n = number of trials

x = number of successes among n trials

p = probability of success in any one trial

q = 1 -p

P(x)= p x q n-x n!/[(n-x)!x!]

where n = number of trials

x = number of successes among n trials

p = probability of success in any one trial

q = 1 -p
