number of successes
-————————————— = 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}
