 Hello. This is a video about how to calculate binomial probabilities. A poll is given showing 65% are in favor of a new building project. If eight people are choosing that random, what is the probability that exactly five are then favor the new building project? So at the end of the day, I'm trying to find the probability that exactly five favor the building project exactly five. So the behavior I'm looking at here is favor. So that's what a success is. A success is favoring the project. Well, what's the probability of a success? What's the probability that somebody will favor the new project one person at 65% or a point 65? So I'm going to calculate my probability in Google Sheets of exactly five. But I need to know the total number of trials, which is eight probability of a success. Then I need a lower and upper bound. This is the range of successes I'm looking at. I'm looking at only exactly five. So the lower bound and upper bound both need to be five. So this is what we put into Google Sheets. Google Sheets, you go to the compute tab. The binomial region type in your number of trials, which is eight probability of a success point 65 and lower bound and upper bound both of five. Looks like you get 0.2786. 0.2786 we round the four decimal places. 0.2786. 0.2786 is your answer.
