When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a randomly chosen ball is not green we will use the Probability Formula.
P=Favorable Outcomes/Possible Outcomes
In the bucket, there is a total of 7 yellow, 6 green, 3 blue, and 8 red balls. The sum of these values is the number of possible outcomes.
7 + 6 + 3 + 8 = 24 balls
The number of favorable outcomes is the sum of the yellow, blue, and red balls.
7 + 3 + 8 = 18balls
Now we have enough information to calculate P(not green).
