In a Binomial Distribution, If N = 20 and Q = 0.75, Then Write Its Mean. - Mathematics

Question

In a binomial distribution, if n = 20 and q = 0.75, then write its mean.

 

Solution

n= 20 , q =0.75

\[\Rightarrow p = 1 - q = 0 . 25\]
\[\text{ Mean = np } = 20(0 . 25) = 5\]
\[\text{ Thus, mean } = 5\] 

  Is there an error in this question or solution?
