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.

Answer 2

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).
