Question

mean of binomial (4,1/2) distribution=​

Answer 1

Answer:

The answer is 2

Step-by-step explanation:

Concept:

Binomial distribution probability with number of trials $n$ and probability of success $p$ denoted by $B(n,p)$ and its mean is given by $np$

Here for B(4,1/2)

   $n=4,p=\frac{1}{2}$

Thus mean $=np=4(\frac{1}{2})=2$
