Multiple Choice

Certain

Likely

Unlikely

Impossible

Equally Likely

Multiple Choice

How likely is it that summer will come?

Probability Scale

0% = Impossible to happen
25% = Unlikely
50% = Even Change
75% = Likely
100% = Certain

Drag and Drop

The probability scale falls between

at lowest end and

at highest end

OR 0% and

percent

Drag these tiles and drop them in the correct blank above

Match

Match each event with its likelihood

impossible

Unlikely

As likely as not

Likely

Certain

A pig flying.

Picking a face card from a deck of cards.

Getting heads on a coin toss.

A sum greater than 4 when rolling 2 dice.

Rolling a number less than 7 on a die.

Labeling

Place each word on the probability scale

Drag labels to their correct position on the image

Unlikely

Certain

As likely as not

Impossible

Likely

Probability of Simple Events

Part (want).

Total (have)

***Always reduce/simplify

For example...

IF I toss a quarter, what is the probability that I will get heads? This is really asking what is the chance that I will land on heads?

What is the probability?

When you toss a coin, the chance that it will land on heads is 1 out of 2. This is because there is 1 side that is heads and there are two total options.

Different ways to write probability

You could say that there is a 1/2 chance or 1 out of 2 chance or 50% chance

Probability of the Spinner

Look at the spinner at your right.
How many possible outcomes are there?

Multiple Select

What is the probability of the spinner landing on blue?

2/10

1/5

2/8

Multiple Choice

Mrs. Trevino has 3 red pens, 5 pink pens, and 8 blue pens. What is the probability that she will choose a blue pen to grade papers?

1/2

3/16

16/8

Multiple Choice

A bag contains 15 yellow cubes, 6 blue cubes, and 4 red cubes. If you select a cube at random, what is the probability the cube will NOT be yellow?

25/15

2/5

5/3

How do you know if it is a complement problem?

When it says: Not [event]
Ex: What is the probability of Not rolling a number greater than 4?
Ex: P(Not greater than 4)

Multiple Choice

What is the probability of Not spinning blue?

P(Not Blue) = 1/4

P(Not Blue) = 1/2

P(Not Blue) = 2/3

P(Not Blue) = 3/4

Multiple Choice

What is the probability of NOT rolling a Prime Number?

0/6

1/6

1/2

1/3

Theoretical vs Experimental Probability

Multiple Choice

Theoretical Probability is:

What will happen

What should happen

What I want to happen

What does happen

Theoretical Probability

Experimental Probability

Multiple Choice

Experimental Probability is:

What will happen

What should happen

What I think happens

What does happen

Multiple Choice

inThe bar graph shows the results of spinning the spinner 200 times. What is the experimental probability of landing on a 3?
