Analyzing data, you found that the probability that a computer user clicks on the online ad of your company is 0.22 or 22% (a person either clicks or does not click on your ad). Let X be the number of independent people who view the ad until someone clicks on it (including the person who clicked on the ad, so if we say X=5, that means it took 5 people to look at the ad to get one to click on the ad). Say you show the ad to 20 independent people. Let Y be the number of people who click on the ad among the 20 independent people who view the ad Let Z be whether a person who views the ad clicks on it or does not click on it.
