If n = 15 and p = 0.4, then the standard deviation of the binomial distribution is?

Solution:

It is given that

n = 5, p = 0.4

We have to find the standard deviation of the binomial distribution

The formula to find the SD of binomial distribution

σ = √npq

Where n is the number of trials

p is the probability of success

q is the probability of failure = 1 - p

Substituting the values

σ = √(5)(0.4)(0.6)

σ = √1.2

σ = 1.095

Therefore, the standard deviation of the binomial distribution is 1.095

If n = 15 and p = 0.4, then the standard deviation of the binomial distribution is?

Summary:

If n = 15 and p = 0.4, then the standard deviation of the binomial distribution is 1.095
