Hi, this is Aaron, a graduate of University of the Arts in Philadelphia, Pennsylvania. I got my BFA in drawing and painting, and today, I'm going to show you how to draw a tree diagram. Today, I'll be using charcoal pencils. Any marks that you're unhappy with can be erased using a couple of erasers. Alright, now, to start your diagram, let's say you flip a coin. So, over here, what happens when you hit "heads", and down here, will be what happens for "tails". Now, a different variable if you want to throw in for more outcomes would be to roll a die. So, with a die, you have six possible outcomes for each side of the coin: One, two, three, four, five, and six. And again, two, three, four, five, six. So, what each of that's going to do, with a roll of your die, is give you a different range of outcomes, which you can plot right in a row, in a column, really, from top to bottom. Heads one, heads two, heads three and four, and heads five and six. Then, of course, the inverse of that is Tails one, two, three, four, five, and six. This has been Aaron Wemer, showing you how to draw a tree diagram.
