• SWBAT:

• Define probability, event& outcomes

• Determine the probability of a “favorable” even occurring

### Probability, Events and Outcomes

Yoyoyo welcome back!!!!!!!! Happy NEW YEAR!

An experiment is a situation involving chance or probability that leads to results called outcomes.

Ex: …. In the problem above, the experiment is spinning the spinner. Do you agree?!

An outcome is the result of a single trial of an experiment.

The possible outcomes are landing on orange, blue, green or red.

An event is one or more outcomes of an experiment.

One event of this experiment is landing on blue.

Probability is the measure of how likely an event is.

The probability of landing on blue is one-fourth.

Blue blueblueis my favorite color (presently).

To land on BLUE would be a “favorable” outcome for me.

• Probability Of An Event P(A) =

Probability is the measure of how likely an event is.

What’s the probability of landing on yellow?

Red?

• A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a red marble? a green marble? a blue marble? a yellow marble?

• What are the possible outcomes?....

Fundamental Counting Principle marbles. If a single marble is chosen at random from the jar,

How many different types of sandwiches can we make?

Choices:

Wheat Roast beef American

Sourdough Turkey Cheddar

Ham Swiss

Fundamental Counting Principle marbles. If a single marble is chosen at random from the jar,

• How many different phone numbers

can exist with a 617 area code before

a new area code needs to be created?

Exit Ticket marbles. If a single marble is chosen at random from the jar, 

• 1. Which of the following is an experiment?

• Tossing a coin. c. Choosing a marble from a jar.

• Rolling a single 6-sided die d. All of these

• 2. Which of the following is an outcome?

a. Rolling a pair of dice c. Choosing two marbles from a jar

• Landing on red

• 3. Which of the following experiments does NOT have equally likely outcomes?

• Choose a # at random from 1-7 c. Choose a letter at random from the word SCHOOL

• Toss a coin d. None of these

• 4. What is the probability of choosing a vowel from the alphabet?

• 5. A number from 1 -11 is chosen at random. What is the probability of choosing an odd number?
