Concept explainers
Describe how you would use the geometric probability model to design a stimulation.
Explanation of Solution
Given:
According to a survey, people buy 30% of their books in October, November, and December , 22% during January, February, and March, 23% during April , May, and June, and 25% during July, August, and September.
Calculation:
Step 1 :
Possible Outcomes | Theoritical Probability |
People buy books in October, November, and December | 30% |
People buy books in January, February, and March | 22% |
People buy books in April , May, and June | 23% |
People buy books in July, August, and September | 25% |
Step 2:
The simulation will consist of 100 trials.
Step 3:
We can use a spinner divided into four sectors :
one containing 30% of spinner’s area , second containing 22% of spinner’s area , third containing 23% of spinner’s area , and the fourth containing 25% of spinner’s area .Find the measurement of central
People buy books in October, November, and December =
People buy books in January, February, and March =
People buy books in April , May, and June =
People buy books in July, August, and September =
: Red sector
Step 4:
A trial means one spin on the spinner , represents the month in which books are bought .
The simulation will consist of 100 trials.
Perform 100 trials and record the result.
