Sixty percent of the people surveyed use sunscreen. A random number generator was used to simulate the results of asking the next three people. The numbers 0â5 represent people who use sunscreen, and the numbers 6â9 represent people who do not use sunscreen. What is the probability that two of the next three respondents use sunscreen?
P(Sunscreen)= 5/10 or 50%

You shoot 70% from the free throw line normally, so you do a simulation using a spinner where 0-6 represent a make, and 7-9 represent a miss. You perform 8 trials on making your next 4 free throws, the results are,
1468, 3288, 9735, 1337, 4825
Based on your simulation, what is the probability you make 75% of your next 4 free throws?
3/5 or 60%

You flip a quarter 50 times, and it lands on heads 33 times. you flip a nickel 40 times and it lands on tails 27 times. How does this affect the theoretical probability of landing on heads for a quarter compared to a nickel?
It doesn't. The theoretical for both is 50%

To win a game at the fair you must spin "4" on both spinners. What is the probability of winning?
P(4)= 1/8*1/4=1/32
or
3.125%

Mr. O'Toole uses a name spinner online to select one of his 5 students to put their work on the board. The spinner reads "Adam, Brynlie, Adam, Camryn, Adam, Lia, Adam, Megan, Adam, Adam" Is Mr. O'Toole being fair? What is the probability Megan is selected?
No, there are more Adam's than anyone else.
1/10 or 10%

Lunches can be made consisting of exactly one entrée, one drink, and one snack.
If all lunch options are equally likely, what is the probability of randomly choosing a lunch that
• does not contain the veggie wrap
• has milk or water, and
• has fruit as the snack.
Write your answer as a percentage, to the nearest percent.
15%
