Simulations: Day 2

A basketball player makes 80% of his free throws. The random numbers represent 20 trials for a simulation. Let the numbers 0 to 7 represent a made free throw and let 8 to 9 represent a missed free throw. Use the simulation to calculate the experimental probability that the player will make both free throws.

• 55%

• 70%

• 85%

Students are asked to use the simulation numbers to estimate the probability that exactly one person says he or she enjoys the beach. Let the numbers 0-5 represent a person who enjoys going to the beach and let 6-9 represent a person who does not. Use the simulation to estimate the experimental probability that exactly one person enjoys the beach as a percentage.

• Do Vote: 0 to 5; Don't Vote: 6 to 9

• Do Vote: 0 to 9

• Do Vote: 0 to 3; Don't Vote: 4 to 9

At a startup company there is a 30% chance an item is defective. The random numbers represent 10 trials for a simulation. Which of the following assigned numbers, for defective and not defective items, can be used for the simulation model?

• Defective: 0 to 4; Not Defective: 5 to 9

• Defective: 0 to 2; Not Defective: 3 to 9

• Defective: 0 to 3; Not Defective: 4 to 9

• Defective: 0 to 2; Not Defective: 3 to 10

Wanda used a number cube to simulate a flower seed sprouting for which the success rate is 50%. She used even numbers to represent success and odd numbers to represent failure. The results of 8 trials are shown. Based on the simulated results, what is the probability that none of the next five flower seeds will sprout successfully?

• $\frac{1}{8}$

• $\frac{5}{8}$

• $\frac{3}{8}$

• $\frac{1}{4}$

• $1$

Dennia is successful on 80% of free throws she attempts. She uses the spinner to simulate her next four attempts. Sections labeled 1 to 4 represent successful attempts, and the section labeled 5 represents missed attempts. For how many of the 5 simulated trials do the data predict exactly 2 successful baskets?
