Step 1
The formula of binomial probability is defined as:
P(X)=n!X!(nX)!px(1p)nX
Given:
n=15
p=0.3
x=0
Step 2
Substitute the given values in the formula of binomial probability.
The calculations are shown below:
P(0)=15!0!(150)!0.30(10.3)150
The answer is 0.0047.
Therefore, the required probability is 0.0047.
