Geometry Unit 8 Review

These flashcards cover various probability concepts and calculations based on a geometry review lecture.

What is the probability of picking a blue marble from the bag?

P(blue) = 4/10 or 2/5.

What is the probability of not picking a green marble from the bag?

P(not green) = 6/10 or 3/5.

What is the probability of not picking a red marble from the bag?

P(not red) = 9/10.

What is the probability of picking a green marble from the bag?

P(green) = 3/10.

What is the experimental probability of the spinner stopping on section A?

P(A) = 4/12 or 1/3.

What is the theoretical probability of the spinner stopping on section C?

P(C) = 1/4.

What error did your friend make when predicting the theoretical probability of getting heads?

They believed it is based on experimental results instead of the formula.

What is the correct theoretical probability of getting heads when flipping a coin?

P(heads) = 1/2.

Estimate the number of away team fans at the Seahawks game with 66,960 attendees.

Estimated = (2/240) * 66960 = 560.

Estimate the number of away team fans at the Seahawks game with 50,800 attendees.

Estimated = (2/240) * 50800 = 423.

What is the experimental probability of rolling a 5 on a standard number cube?

P(5) = 5/8.

If you roll a standard number cube 40 times, how many rolls do you predict will be fives?

Predicted = (5/8) * 40 = 25.

What is P(N) when choosing a letter from the word ASSIGNMENT?

P(N) = 2/11.

What is the probability of not picking an M from the word ASSIGNMENT?

P(not M) = 9/11.

What is the probability of not picking an S from the word ASSIGNMENT?

P(not S) = 9/11.

USA: 46, Great Britain: 27, China: 26, Russia: 19.

What is the frequency for the number of free throws made by 16 friends?

0: 8, 1: 3, 2: 4, 3: 1.

Calculate P(dog | lives outside) from the two-way frequency table.

P(dog | lives outside) = 17/25.

What is P(cat) from the two-way frequency distribution?

P(cat) = 16/40 or 2/5.

Calculate P(cat | lives inside) from the two-way frequency table.

P(cat | lives inside) = 8/15.

Calculate P(cat that lives inside) from the two-way frequency table.

P(cat that lives inside) = 8/40 or 1/5.

Calculate P(dog that lives inside) from the two-way frequency table.

P(dog that lives inside) = 7/24.

Calculate P(lives outside | cat) from the two-way frequency table.

P(lives outside | cat) = 8/16 or 1/2.

What is the probability of living inside?

P(lives inside) = 15/40 or 3/8.

Calculate P(live inside | dog) from the two-way frequency table.

P(live inside | dog) = 7/24.
