In a Probability Simulation

The questions on a multiple choice test each have 6 answer choices. Which model can be used to simulate randomly selecting the correct answer on a 20 question multiple choice test?

• rolling a six-sided number cube 6 times

• rolling a six-sided number cube 20 times

• spinning a spinner with 4 equal sized sections 4 times

• choosing 1 marble in a bag of 20 different colored marbles

Layla has 2 pairs of shoes and 6 pairs of socks. If each pair of socks and each pair of shoes is equally like to be chosen, which is the best simulation to show the probability of choosing any given combination?

• roll a die and flip a coin

• roll a die two times

• flip a coin 6 times

• flip a coin 2 times

Samuel has 5 different colors of pens and 2 different colors of paper. Which model could be used to show how many different choices he has?

• spin a spinner with 5 sections, then flip a coin

• roll a die 5 times

• flip a coin 5 times

• roll a die, then flip a coin 5 times

An ice cream parlor offers 15 different flavors of ice cream. Which model could be used to show how many different choices there are?

• spin a spinner with 5 sections

• flip a coin

• spin a spinner with 15 sections

• roll a die and flip a coin

A way to model random events, so that outcomes closely match real-world outcomes is called a(n) ________________.

Based on the results of this simulation, when 3 people are randomly selected, exactly 2 right-handed people are selected approximately ____% of the time.

• 20%

• 25%

• 18%

• 22%

A cereal company is placing one of 6 different tickets into its boxes of cereal. If each ticket is equally likely to appear in a box of cereal, which model could be used to simulate the tickets you would find in 50 boxes of cereal?

• a coin that is flipped 50 times

• a spinner that has 4 sections that is spun 50 times

• a number cube that is rolled 50 times

• a coin is flipped and a number cube is rolled 50 times 

A class quiz has 5 True/False questions. The correct answers are T, T, F, F, and T, in that order. Brandon answered the questions randomly and is now wondering if he will pass the quiz.

He needs to have at least 3 correct answers. Brandon used a calculator to generate random numbers from 1 to 100. He let odd numbers stand for True and even numbers stand for False. He recorded the results in the table. What is the experimental probability that John passed the quiz? Use the chart to answer the question.

To determine what letter will be used in a game of Scattegories (where a letter is chosen at random), Mr. Glass sets up a simulation. He wants to determine how likely it is that a vowel is chosen both times if they play the game twice. How should he set up his simulation?

• Use 1-5=vowel, 6-26=non vowel. Choose 5 numbers from 1-26

• Use 1-5=vowel, 6-10=non vowel. Choose 2 numbers from 1-10

• Use 1-5=vowel, 6-26=non vowel. Choose 2 numbers from 1-26

• Use 1-5=vowel, 6-10=non vowel. Choose 5 numbers from 1-10
