Activities

  1. What is the probability of not rolling an odd number on a number cube?
  1. A weather forecaster states that there is a 61% chance of rain tonight. What is the probability that it will not rain tonight?
  1. A vendor has 15 helium balloons for sale: 7 are yellow, 4 are blue, and 4 are red. A balloon is selected at random and sold. If the balloon sold is yellow, what is the probability that the next balloon selected at random is also yellow? Show your work.
  1. Nick is taking a test and has to guess on two of the answers.  The first question was a yes or no answer, and the second question was a multiple choice problem that had four answers to pick from.  What is the probability that he will get both questions correct by guessing?  Show your work.
  1. The menu for the high school cafeteria is shown below.

Part (A): Determine the number of possible meals consisting of a main course, a vegetable, a dessert, and a beverage that can be selected from the menu. Show your work.

Part (B): Determine how many of these meals will include pizza. Show your work.

Part (C): If a student chooses a sandwich, vegetables or fruit, a dessert, and a beverage from the menu, determine the number of possible meals that can be selected. Show your work.

  1. Will wants to make two game spinners in which the chance of landing on blue will be twice the chance of landing on red and landing on green will occur more than 25% of the time.

    PART (A):  Label each section either blue (B), red (R), or green (g) to show how Will could label his spinner.

PART (B): Create a different spinner following the same guidelines that will used.

Answer Key/Rubric

  1. 3 out of 6
  1. 100 – 61 = 39 %
  1. The probability of selling two yellow balloons in a row is 20%.  Student work might include but is not limited to,
  • At first there are 7 yellow out of 15 total
  • Then there is 6 yellow out of 14 total
  • 0.2
  1. Nick has a 1 out of 8 chance of getting both questions correct.  Student work might include but is not limited to,
  • The first question has 2 possible answers so he has a chance of guessing right
  • The second question has 4 possible answers so he has a chance of guessing right

Student work might include but is not limited to,

  1. Part A) You need to multiply all the menu choices to find the total number of meal combinations.
    5 x 3 x 4 x 4 = 240.

    Part B) You need to multiply one for pizza meals by the sides, desserts, and drinks.                               
    1 x 3 x 4 x 4 = 48.  So 48 out of 240 meals in the school include pizza.

    Part C ) You would need to multiply the numbers that represent the amount of items in each categories.  1 x 2 x 4 x 4 = 16. 
  1. Part A) Spinner labels may be labeled in a different order

Part B) Answers will vary, student work might include but is not limited to
