• You and a partner will create a game involving some form of probability.• You will need to have rules (explained)• What are the possible outcomes?• How does a player win a game?• What probabilities are important to know? Justify your response.• What strategies might you use to increase your chance of winning? Justify

your response.• Speed Gaming will occur• If you lose you pay the other player 5 dollars (fake money)• This will occur over 2 days.• Teams that collect the most money over 2 days will a trophy!!

Anchor ActivityEXAMPLES OF PROBABILITY GAMES

1. Don’t roll the number (use table)2. Is it a match? (Page 194) – counters (red/blue), cups

Probability Student Outcome: I will be able to write probabilities as ratios, fractions and percents.

• Probability: is the likelihood or chance of an event occurring.• Outcome: any possible result of a probability event.• Favourable Outcome: a successful result in a probability event.

(ex: rolling the #1 on a die)• Possible Outcome: all the results that could occur during a probability

event (ex: rolling a die - - #1, #2, #3, #4, #5, #6)

• P = Favourable Outcomes Possible OutcomesWhat is the probability of rolling the number 2 on a dice?• What is the favourable outcome?• How many possible outcomes?

How to express probability

Student Outcome: I will be able to write probabilities as ratios, fractions and percents.

• Probability can be written in 3 ways...

• As a fraction = 1/6• As a decimal = 0.16

• As a percent

0.16 x 100% = 16%

How often will thenumber 2 show upwhen rolled?

Determine the probabilityStudent Outcome: I will be able to write probabilities as ratios, fractions and percents.

First you must find the possible outcomes (all possibilities)and then the favourable outcomes (what you’re looking for). Then place them into the probability equation.

1. Rolling an even number on a die?2. Pulling a red card out from a deck of cards?3. Using a four colored spinner to find green?4. Selecting a girl from your class?

Organized OutcomesStudent Outcome: I will be able to create a sample space involving 2 independent

events.

Independent Events:• The outcome of one event has no effect on the

outcome of another event

Probabilities of Simple Independent Events

Student Outcome: I will learn about theoretical probability.

Random: an event in which every outcome has an equal chance ofoccurring.

A school gym has three front stage doors (left, center, right) and two backstage doors (left, right). During a school play, an actor can enterthrough one of the five doors. The next actor to enter any door can be either a boy or a girl. Use a “Tree Diagram” to show the samplespace. What is the P (probability) that a boy will enter a frontcenter door?

See Page 172 for your “Tree Diagram” of the school gymdoors!

Using a Table to DETERMINE Probabilities


How to determine probabilities:

Probability (P) = favourable outcomes possible outcomes

= decimal x 100%

Use your results from the “tree diagram” of the gym doorsand place them into a chart. Then determine theprobabilities for the chart.



Determine the probability for the school stage door and boy/girl scenario using a chart sample space.

Practical Quiz #2On the front of the paper:Draw a sample space using a chart for the following events.On the back of the paper:Draw a sample space using a tree diagram for the following events.

Rolling a 4 sided die and flipping a quarter.

Applications of Independent Events


Let’s play “Sit & Save?”(page 177)

RULES:1. Stand up at the beginning of the round.2. Two dice are rolled each round. You may collect the sum of

your dice as long as a “6” does NOT appear. A “6” means all numbers before are cancelled and you get zero for that round.

3. After each roll you have two choices• Continue standing and roll again…hoping for no “6”

OR• Sit and collect your total points!

Applications of Independent Events


How can you win at the game of “Sit & Save?”

1. Who had the highest score?2. What is the possibility of a 6 appearing with 2 dice? (sample data)

3. Use the numbers above for each player to find who had the best probability (percent) of not rolling a 6.

2. What is the probability of

3. What is the probability of outcome having one 3 appear?

Interpret OutcomesStudent Outcome: I will learn about theoretical probability.
