Variance of the Bernoulli Distribution | Probability Theory

Показать описание
How do we derive the variance of a Bernoulli random variable? That's what we'll go over in today's probability theory lesson! We'll prove the variance of a Bernoulli random variable with probability of success p is equal to p*(1-p). Remember the variance of a discrete random variable is equal to the expected value of the squared deviation from the mean.

I hope you find this video helpful, and be sure to ask any questions down in the comments!

crystal clear! can't believe most textbooks just tell you that the variance of Bernoulli distribution is p(1-p) and hope you will take it home. It takes great teachers like you to make things simple and intuitive. thanks a lot.
