Construct probability Models

What motivated the person to study the line sizes at the frozen yogurt store?

• They wanted to open their own store

• They disliked waiting and wanted to find the best time to visit

• They were conducting a school project

• They were randomly selected for a survey

How many times did the person find no one in line during their visits?

• 18 times

• 50 times

• 24 times

• 8 times

What is the probability of finding exactly one person in line?

• 0%

• 36%

• 16%

• 48%

If the person visits the store 500 times, how many times are they likely to see a two-person line, based on their estimates?

• 80 times

• 85 times

• 65 times

• 100 times

Why is it important to understand that the calculated probabilities are estimates?

• Because the prices might go up

• Because the yogurt flavors might change

• Because the store might change its opening hours

• Because the actual outcomes can vary
