At a middle school, 30% of students buy lunch in the cafeteria and the remaining students bring lunch from home. A spinner with 10 equal-sized sections numbered 0-9 will be used to simulate the lunch trend. How can you design a simulation to guess whether the next 20 students buy lunch or bring lunch from home?
Assign the numbers 0β3 to represent students who buy lunch and the numbers 4β9 to represent students who bring lunch from home. Spin the spinner 20 times and count how many spins are between 0β3 and how many are between 4β9.
Assign the numbers 0β2 to represent students who buy lunch and the numbers 3β9 to represent students who bring lunch from home. Spin the spinner 10 times and count how many spins are between 0β1 and how many are between 4β6, then multiply the counts by 2.
