Concept #1: Determining the Mean and Standard Deviation of The Binomial Distribution

Concept #2: Determining the Mean and Standard Deviation of The Binomial Distribution: Intro

Practice: A coin is tossed 100 times, what is the standard deviation of the binomial distribution for the number of heads you would end up with?

Practice: If there is a 30% chance of conceiving a boy, how many do you expect to have if you want to have 4 kids?

Practice: You're playing beer pong. You average a 30% miss rate. Out of 6 shots, how many do you expect to make? What is the standard deviation of this binomial distribution?

Practice: Pregnancy scares are serious. If there is a .01% chance that a condom breaks, what is the average number of condoms you'd expect to break out of 100? What is the variance for this distribution?
