Tree DiagramsObjective: Use tree diagrams to
count outcomes and find probabilities
Lab
Number in your notebooks 1-30.
1. Record for each toss whether you get an even or an odd.
2. Determine how many odd tosses you had and then determine how many times you tosses an even.
3. What were your results?
A certain type of scooter comes in silver, red or purple with wheel sizes of 125 mm or 180 mm. Find the total number
of color-wheel size combinations

COINS A game involves flipping two pennies. Draw a tree diagram to show the sample space of the results in terms of heads and tails. Then determine the probability of flipping one head and one tail.
Answer:
ICE CREAM An ice cream sundae at the Ice Cream Shoppe is made from one flavor of ice cream and one topping. For ice cream flavors, you can choose from chocolate, vanilla, and strawberry. For toppings, you can have hot fudge, butterscotch, or marshmallow. Find the number of different sundaes that are possible.

ICE CREAM An ice cream sundae at the Ice Cream Shoppe is made from one flavor of ice cream and one topping. For ice cream flavors, you can choose from chocolate, vanilla, and strawberry. For toppings, you can have hot fudge, butterscotch, or marshmallow. If you are given a sundae at random from the Ice Cream Shoppe, what is the probability that it has vanilla ice cream?Make a tree diagram to show the sample space. Then, find the probability that the sundae has vanilla ice cream.
