Exercise 13 Page 728

When calculating the experimental probability, we are comparing the number of times the event occurs to the number of times the experiment is done. P=Times the Event Occurs/Times the Experiment Is Done Mitch played 30 times in par-3 holes. This means that the number of times the experiment is done is 30.

Mitch's Golf Result
Score	Number of Holes
2	4
3	14
4	9
5	3

We can see that Mitch scored 2 points in 4 holes and 3 in 14 holes. The number of times the event occurs is the sum of these numbers of holes. 4 + 14 = 18 Now we have enough information to calculate P(2or3).

P=Favorable Outcomes/Possible Outcomes

SubstituteValues

Substitute values

P(2or3)=18/30

ReduceFrac

a/b=.a /6./.b /6.

P(2or3)=18/6/30/6

CalcQuot

Calculate quotient

P(2or3)=3/5

The probability of scoring 2 or 3 in the next hole is 35, which corresponds to option B.
