**number of successes**

-————————————— = probability

number of possibilities

-————————————— = probability

number of possibilities

6 yellow + 5 green + 4 red

= 15 total gumballs {number of possibilities}

6 yellow + 4 red

= 10 not green {number of successes}

10

—— = probability of not green {took number of successes over number of possibilities}

15

**P(not green) = 2/3**{reduced}
