Binomial random variables have only two possible outcomes (sample space) and are used to represent repeated events of the same probability.
I can find binomial probabilities using available technology.
In this video, Patrick discusses what a binomial experiment is, discuss the formula for finding the probability associated with a binomial experiment, and do a concrete example which hopefully puts it all together!
Nancy shows how to do a binomial expansion with the Binomial Theorem and/or Pascal's Triangle. To skip ahead:Â 1) for HOW TO EXPAND a BINOMIAL raised to a power, like (x + 3)^5, skip to time 0:57; 2) for how to find the BINOMIAL COEFFICIENTS with the FACTORIAL/COMBINATION formula, skip to time 03:29; 3) to use PASCAL'S TRIANGLE to find binomial coefficients for expansion, skip to time 09:32; 4) for how to write the expansion for a SUBTRACTION/DIFFERENCE binomial raised to a power, skip to time 13:11 - Nancy formerly of mathbff explains the steps.
