Ethan's class is handing out balloon arrangements consisting of 4 balloons each. Each
balloon has an equally likely chance of being red, blue, or yellow. Ethan created a
spinner to simulate this probability. Here is Ethan's data from 30 trials of 4 spins on
the spinner (r = red, b = blue, y = yellow):

According to this data, what is the experimental probability that an arrangement will
not contain any balloons that are red?
