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. It has a fixed number of trials. I'm taking two cards out of the deck, so it seems to meet that. But what about these conditions, that it's made up of independent trials, or that the probability of success on each trial is constant?
