A food truck offers a lunch special.
Customers have a choice of a sandwich
(ham, turkey, or veggie), a side (chips or
pretzels), and a drink (soda or juice). How
many possible outcomes are in the sample

A hat contains cards with different colors.
Annabella randomly selects a card from
the hat and returns the card to the hat
after noting the color. After randomly
selecting a card 300 times, she has picked
a purple card 70 times. Based on her
results, what is the estimated probability
that Annabella selects a purple card?

Dave wants to create a simulation that represents and event with a 25% CHANCE OF occurring. Describe a model he could use.
Possible Answer: A spinner with 4 equal sections, numbered 1-4, where 1 represents the event occurring.

A spinner is divided into 4 sections using
the colors red, orange, green, and blue.
After 50 trials, the spinner has landed on
red 10 times, on orange 16 times, on green
6 times, and on blue 18 times. Based
on the results, what is the estimated
probability that the spinner does not
land on green?

Mickey runs a restaurant. About 45% of
his customers pay with cash and the rest
pay with a credit or debit card. Suppose
Mickey wants to use a random number
generator to simulate the payment
method used by the next 5 customers. If
the generator produces numbers 1
through 20, how many numbers should
be used to represent a customer paying
with cash?

Sia makes 10% of the shots she attempts in soccer at any given time. A random number generator was used to generate 5 sets of random numbers from 1 to 10 as shown, where number 1 represents a successful shot and numbers 2–10 represent a missed shot. Find the experimental probability that Sia will make at least 2 of the next 10 shots. Write your answer as a percent.

Brynlee asks people at a theater how old they are. She finds that 8 out of 75 people are under the age of 12. If there are 2,434 people at the theater, how many people can Brynlee expect to be under the age of 12 based on the experimental probability?

There is a 20% chance that a customer walking into a store will make a purchase. A computer was used to generate 5 sets of random numbers from 0 to 9, where the numbers 0 and 1 represent a customer who walks in and makes a purchase.What is the experimental probability that at least one of the first three customers that walks into the store will make a purchase?

There is a 20% chance that a particular volcano will erupt during any given decade. A random number generator generated 10 sets of random numbers from 1 to 5 as shown. The number 1 represents the volcano erupting. Find the experimental probability that the volcano will erupt in 1 or 2 of the next 5 decades.
Write your answer as a percent.

Edith spun a spinner with 5 equal sections labeled 1–5. The spinner landed on 1 five times, on 2 three times, on 3 four times, on 4 three times, and on 5 five times. For which number is the experimental probability the same as its theoretical probability? Explain.
The theoretical is the same for each number, 20%. The experimental probability for spinning a 3 was
4/20 , which is the same as the theoretical probability, since that equals 20%.
