<h3>What is
a binomial probability distribution?</h3>
Generally, the equation for Binomial expression is mathematically given as
X ~ Binomial (n,p)
Where
n = 8
p =
Generally, the equation for a binomial probability distribution is mathematically given as
P(X) = nCx px (1-p)n-x
P(X = 1) = 8C1 (1/21)1 (20/21)7
x= 0.270736
In conclusion, the probability of obtaining a commercially successful well for the following number of times.
x= 0.270736
