Rory was with some friends outside an ice cream parlor. he noticed that one out of every four people bought a vanilla cone. he wants to know the estimated probability that five randomly picked people entering the shop will not buy vanilla cones. how could you design a simulation of the scenario?

a) spin a spinner with five equal sections five times. on the spinner, one section represents vanilla and four sections represent other flavors.

b) spin a spinner with five equal sections four times. on the spinner, one section represents vanilla and four sections represent other flavors.

c) spin a spinner with four equal sections five times. on the spinner, one section represents vanilla and three sections represent other flavors.

d) spin a spinner with four equal sections four times. on the spinner, one section represents vanilla and three sections represent other flavors.

Since the ratio is one out of four, you can throw out the first two (a and b). We then look to "c" and we find that the spinner represents the correct ratio, and since we are going to predict the next 5 people, that would be 5 spins (which eliminates d).
