2. Theoretical and Experimental Probability
Sign In
Use the experimental probability.
B
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).
Substitute values
a/b=.a /6./.b /6.
Calculate quotient
The probability of scoring 2 or 3 in the next hole is 35, which corresponds to option B.
