A spinner is divided into 12 equal sections where 5 of the sections are red, 3 are blue, 2 are orange, and 2 are green. What are the frequencies of each color if you spend the spinner 60 times?

  1. Reiny

    prob(red) = 5/12
    prob(blue) = 3/12
    etc for the other colours.

    then multiply each prob by 60

    you can check your answer by making sure all the prob's above add up to 1
    and the sum in the colour distribution is 60
