So this says a manager oversees 11 female employees and nine male employees. They need to pick three of these employees to go on a business trip, so the manager places all 20 names in a hat and chooses at random. Let x equal the number of female employees chosen. So they're going to do three trials, and on each of those trials, you could say success is if they pick a female employee, and then the random variable x is the number of females out of those three. Is x a binomial variable? Why or why not? So pause this video and see if you can work through this on your own.
