VOCABULARY DEFINITION EXAMPLE

EXPERIMENT

An actvitity involving chance

that can have different results.

Flipping a coinRolling a die

OUTCOME

The different results that can

occur in an experiment

Flipping a coin:Heads or tails

Rolling a die:1,2,3,4,5,6

SAMPLE SPACE

The set of all possible outcomes. You can use { } to

show sample spaces

Flipping a coin:{Heads or tails}

Rolling a die:{1,2,3,4,5,6}

EXPERIMENTAL PROBABILITY

The ratio of the number of times

the event occurs to the total number of

times the experiment is

performed

Flipped a coin 4 times

Heads landed 3 times

Probability ¾

For each experiment, identify the outcome shown and the sample space.

outcome: red outcome: yellow

sample space: {red, blue} sample space: {red, blue, yellow}

Kerry has a bag of marbles. He removed one marble, recorded the color, and placed it back in the bag. He repeated this process 15 times and recorded his results in the frequency table.

Color Selected Red Blue Black Green

Frequency 3 1 5 6

3. Find the experimental probability that a marble selected from the bag will be blue. 1

154. Find the experimental probability that a marble selected from the bag will be black. 5 = 1

6. Based on Kerry’s experiment, which color marble is he least likely to select from the bag? blue

7. In 10 free throws, Pamela made 3 shots. What is the experimental probability that Pamela will make her next free throw? 3 = 30% 108. Juan tossed a fair coin and it landed heads up. What is the outcome and sample space of this experiment? outcome: heads

sample space: {heads, tails}

For each experiment, identify the outcome shown and the sample space.

outcome: green outcome: 2

sample space: {red, blue, green} sample space: {1,2,3,4,5}

Amanda has a standard deck of playing cards. She picked one card, recorded the suit, and placed it back in the deck. She repeated this process several times and recorded her results in the table.

3. Find the experimental probability that a card 5 selected from the deck will be a spade. 24

4. Find the experimental probability that a card 4 = 1selected from the deck will be a diamond. 24 6

5. Based on Amanda’s experiment, which card suit is she most likely to select from the deck? club

6. Based on Amanda’s experiment, which card suit is she least likely to select from the deck? diamond
