1. Bellwork: 5/13/16

1. rolling a 6 on a number cube.
2. rolling an odd number on a number cube.
3. flipping two coins and both landing tails up
*Worksheet due today, if you are not finished, you will have time after the quiz

4. Independent and Dependent Events
Find the probability of independent events.
Find the probability of dependent events.

6. Events are independent events if the occurrence of one event does not affect the probability of the other. Events are dependent events if the occurrence of one event does affect the probability of the other.

8. Tell whether each set of events is independent or dependent
Tell whether each set of events is independent or dependent. Explain you answer.
A. You select a card from a standard deck of cards and hold it. A friend selects another card from the same deck.
B. You flip a coin and it lands heads up. You flip the same coin and it lands heads up again.
C. A number cube lands showing an odd number. It is rolled a second time and lands showing a 6.
D. One student in your class is chosen for a project. Then another student in the class is chosen.

11. An experiment consists of randomly selecting a marble from a bag, replacing it, and then selecting another marble. The bag contains 3 red marbles and 12 green marbles. What is the probability of selecting a red marble and then a green marble?

12. A coin is flipped 4 times. What is the probability of flipping 4 heads in a row.

13. An experiment consists of spinning the spinner twice
An experiment consists of spinning the spinner twice. What is the probability of spinning two odd numbers?

14. Suppose an experiment involves drawing marbles from a bag
Suppose an experiment involves drawing marbles from a bag. Determine the theoretical probability of drawing a red marble and then drawing a second red marble without replacing the first one.
Probability of drawing a red marble on the first draw
Probability of drawing a red marble on the second
draw

17. A snack cart has 6 bags of pretzels and 10 bags of chips
A snack cart has 6 bags of pretzels and 10 bags of chips. Grant selects a bag at random, and then Iris selects a bag at random. What is the probability that Grant will select a bag of pretzels and Iris will select a bag of chips?

18. A bag has 10 red marbles, 12 white marbles, and 8 blue marbles
A bag has 10 red marbles, 12 white marbles, and 8 blue marbles. Two marbles are randomly drawn from the bag. What is the probability of drawing a blue marble and then a red marble?
