1 The spinner is spun 12 times. It lands on blue 1 time. What is the experimental probability? Station 1 Yellow   Blue  Red Green 

2 A coin is tossed 100 times and lands on heads 65 times. Compare the experimental and theoretical probability. a. The theoretical probability ½ is greater than the experimental probability of 13/20. b. The experimental probability 13/20 is greater than the theoretical probability of ½. c. The theoretical probability and the experimental probability are the same. d. There is not enough information to compare. Station 2

3 A number cube is rolled 20 times and it landed on “4” six times. Compare the experimental and theoretical probability. A number cube is rolled 20 times and it landed on “4” six times. Compare the experimental and theoretical probability. a. The theoretical probability 1/6 is greater than the experimental probability of 3/10. b. The experimental probability 3/10 is greater than the theoretical probability of 1/6. c. The theoretical probability and the experimental probability are the same. d. There is not enough information to compare. Station 3

4 A bag contains 9 red marbles, 5 green marbles and 6 blue marbles. DaShawn will randomly pick 2 marbles out without replacement. What is the probability that DaShawn will pick a red first and then a blue? Station 4

5 The table shows Alondra’s workout schedule last week. Based on the table what is the probability that Alondra will not run this week. Station 5 Day of the weekExercise schedule MondayCrossfit 60 minutes TuesdayCrossfit 60 minutes WednesdayRun 90 minutes ThursdayCrossfit 60 minutes FridayCrossfit 60 minutes SaturdayRun 90 minutes Sundayrest

6 Station 6 The table shows the results of an experiment Carrie conducted using a box of colored marbles. Based on table, which conclusion can be made? a.The probability of selecting a pink is as likely as yellow b.The probability of selecting green is less likely as yellow c.The probability of selecting blue is greater than green d.The probability of selecting a pink is as likely as green ColorPinkPurpleBlueGreenYellow # of times selected 11195114

7 There is a 1 in 4 chance that Sam will place first in the 300 meter dash at the track tournament. How likely is it that Sam will not place first the race? a. certainc. as likely to happen as not b. likelyd. impossible Station 7

8 There are six equally likely outcomes if a number cube with sides labeled 1 through 6 is rolled. Determine the probability of rolling a 6. How likely is it to land on 6? a. certain c. as likely to happen as not b. unlikelyd. impossible Station 8

9 Station 9 Yesterday, 75 HEB customers bought apples and 15 of those customers bought gala apples. If 300 customers buy apples tomorrow, predict the number of customers you would expect to buy gala apples.

10 Station 10 The local weather forecaster says she can predict rain with 80% accuracy which is equivalent to a 0.8 chance of being correct. If she forecasts rain 160 times, how many of these times would you expect she is wrong?
