This is because the number of non-users is large compared to the number of users. The number of false positives outweighs the number of true positives.
So the engine will come in two different varieties. So you could get a red car. Let me do that in actual red color, or close to red. You could get a red car, you could get a blue car, you could get a green car, or you could get a white car.
So all of these are equally likely. So I encourage you to pause the video and think about it on your own. Well, one way to think about this is, well, what are all the equally likely possible outcomes? And then which of those match six-cylinder white car?
Well, first, we could think about the engine decision. So the first decision is the engine. You could view it that way. Red, blue, green, or white. So how many possible outcomes are there? Well, you could just count. You could kind of say, the leaves of this tree diagram-- one, two, three, four, five, six, seven, eight possible outcomes.
And that makes sense. You have two possible engines times four possible colors.
|CP Statistics - Mr. Hemphill's RHS Math||All collections of events must be mutually exclusive of one another, The probability of intersections of these events must be equal to the product of their individual probabilities.|
You see that right here-- one group of four, two groups of four. So this outcome right here is a four-cylinder blue car. And this outcome over here is a six-cylinder green car. And which outcome matches the one that we, I guess, are hoping for, the white six-cylinder car? We could have thought about color as the first row of this tree.Determine complementary probabilities.
Use Venn Diagrams to illustrate relationships between events. Vocabulary: Tree diagrams displays all outcomes for a event or a series of events.
Calculate binomial probabilities. Vocabulary: Binomial Probability Distribution – a discrete (integer only) probability distribution that meets four. Learning Objectives Chapter 3: Probability LO 1.

The first to win two sets wins the match. The first to win two sets wins the match. Illustrate the sample space using a tree diagram.
The most important concepts from this chapter are those of independence, conditional probabilities, and Baye’s Rule. Also the use Tree Diagrams to map out probabilities associated with two stage experiments should be reviewed.
