Let’s Change Gears! At a sporting goods store, skateboards are available in 8 different deck designs. Each deck design is available with 4 different wheel assemblies. How many skateboard choices does the store offer? Lets make a tree diagram!
3
cont… What else could you do to find the solution?
Multiply # of deck designs by the number of wheel assemblies 4•8 = 32 skateboard choices

The Multiplication Counting Principle
If one event can occur in m ways and another event can occur in n ways, then the number of ways that both events can occur together is m•n. This principle can be extended to three or more events.
5
Dice When rolling a die twice, what is the probability of getting a 1 then a 4?
6
Cards Two cards are drawn from a deck. What is the probability of those cards being a Jack and a 2?
7
Spinners A spinner is spun twice. What is the probability of getting a red then a blue?
