Lesson 10-6: Simulate Chance Events — Practice Questions

  1. 1. A simulation of a soccer player taking penalty kicks was run 80 times. The player scored a goal in 52 of the trials. What is the experimental probability of scoring? Express your answer as a decimal. ___

  2. 2. A computer program simulates a traffic light's behavior. Out of 200 simulated cycles, the light is green for 90 of them. What is the experimental probability that the light will be green, expressed as a percentage?

    • A. 40%
    • B. 45%
    • C. 50%
    • D. 90%
  3. 3. A simulation is used to test a new type of battery. In 400 trials, 6 batteries were found to be faulty. Based on this simulation, what is the experimental probability of a battery being faulty? Express as a decimal. ___

  4. 4. To find the experimental probability of an event from a simulation, which calculation should be performed?

    • A. Divide the total number of trials by the number of successful trials.
    • B. Divide the number of successful trials by the total number of trials.
    • C. Multiply the number of successful trials by the total number of trials.
    • D. Subtract the number of successful trials from the total number of trials.
  5. 5. A simulation models a spinner with different colored sections. Out of 150 spins, the spinner landed on blue 45 times. What is the experimental probability of landing on blue? Express your answer as a decimal. ___

  6. 6. A soccer player scores on $25\%$ of his penalty kicks. Which tool would be the best choice to simulate whether he scores on his next kick?

    • A. Flipping a coin
    • B. Rolling a 6-sided die
    • C. A spinner with 4 equal sections
    • D. A spinner with 6 equal sections
  7. 7. A survey shows that $50\%$ of students prefer pizza for lunch. To simulate this using a 6-sided die, you would assign ___ outcomes to represent preferring pizza.

  8. 8. A weather forecast states there is a $\frac{1}{6}$ chance of snow. A meteorologist wants to simulate this. Which of the following is an appropriate model?

    • A. Flipping a coin and assigning 'Heads' to snow.
    • B. Using a spinner with 4 equal sections, with one section for snow.
    • C. Rolling a standard 6-sided die, with the number 1 representing snow.
    • D. Drawing a card from a deck of 5 cards, with one card for snow.
  9. 9. Each box of a certain brand of tea contains one of 4 unique, equally likely coupons. To simulate collecting one coupon using a random number generator, you should generate numbers from 1 to ___.

  10. 10. A quality check finds that $50\%$ of light bulbs from a factory are long-lasting. To simulate this, a coin is flipped. 'Heads' means long-lasting. What is the probability of 'Heads' in this model?

    • A. $25\%$
    • B. $50\%$
    • C. $75\%$
    • D. $100\%$
