Exercise 24 Page 718

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 mint is orange we will use the Probability Formula. P=Favorable Outcomes/Possible OutcomesIn the bowl, there is a total of 5 red, 3 orange, 1 yellow, and 6 green mints. The sum of these values is the number of possible outcomes. 5 + 3 + 1 + 6= 15 balls The number of favorable outcomes is the number of orange balls, which is 3. Now we have enough information to calculate P(orange).

P=Favorable Outcomes/Possible Outcomes

SubstituteValues

Substitute values

P(orange)=3/15

ReduceFrac

a/b=.a /3./.b /3.

P(orange)=3/3/15/3

CalcQuot

Calculate quotient

P(orange)=1/5

The probability of choosing an orange mint is 15, which corresponds to option A.
