Can you give me an example of something that is not a binomial variable? Well, let's say that I were to define the variable Y, and it's equal to the number of kings after taking two cards from a standard deck of cards, a standard deck, without replacement, without replacement. So you might immediately say, well, this feels like it could be binomial. We have each trial can be classified as either a success or failure. For each trials, when I take a card out, if I get a king, that looks like that would be a success. If I don't get a king, that would be a failure. So it seems to meet that right over there.
