Counting Outcomes with Tree Diagrams

The video tutorial explains a scenario where a person wins a contest at a car dealership and receives a new car. The car's engine type and color are determined randomly. The engine can be either a four-cylinder or a six-cylinder, decided by a coin flip. The car color is chosen from red, blue, green, or white, with each color equally likely. The tutorial explores the probability of receiving a six-cylinder white car using a tree diagram. It demonstrates how to calculate the probability by considering all possible outcomes and highlights an alternative method for constructing the tree diagram.

What are the two types of engines mentioned?

• V6 and V8

• Electric and Diesel

• Two-cylinder and Four-cylinder

• Four-cylinder and Six-cylinder

What action determines the engine type?

• Rolling a dice
