Concept explainers
Design a simulation that can be used to estimate the probability that an athlete will play each of these sports.
Explanation of Solution
Given:
A survey at a high school found that 15% of the athletes at the school play only volleyball , 20% play only soccer, 30% play only basketball, and 35% play only football.
Calculation:
Step 1 :
Possible Outcomes | Theoritical Probability |
Volleyball | 15% |
Soccer | 20% |
Basketball | 30% |
Football | 35% |
Step 2:
The simulation will consist of 100 trials.
Step 3:
We can use a spinner divided into four sectors :
one containing 15% of spinner’s area , second containing 20% of spinner’s area , third containing 30% of spinner’s area , and the fourth containing 35% of spinner’s area .Find the measurement of central
Volleyball =
Soccer =
Basketball =
Football =
: Red sector
Step 4:
A trial means one spin on the spinner , represents the sport .
The simulation will consist of 100 trials.
Perform 100 trials and record the result.
