Question

For a binomial experiment with p = 0.5 and a sample size of 100. The expected value of this distribution is?

Answer 1

a binomial experiment = 0.5 - 100=

99.5

Answer 2

The expected value of this distribution is 50.

Given,

A binomial experiment with p = 0.5 and a sample size of 100.

To find,

The expected value of this distribution.

Solution,

We can simply solve the mathematical problem by the following process.

We know that;

The formula is used to find the binomial distribution is;

E(X) = np  

where,

p = probability of success

n=number of sample size.

Now,

Substitute all the values in the formula;

E(X) = np

E(X) = (100)(0.5)

E(X) = 50

Hence, The expected value of this distribution is 50.
