Answer to Problem 2CYU
The probability that a gym member signs up for the tae kwon do class is
Explanation of Solution
Given information:
Class | Frequency |
Tae kwon do | |
Yoga | |
swimming | |
Kick-boxing |
Calculation:
The following table describes the four classes at a gym and the percentage of gym members that sign up for each class.
Class | Frequency |
Tae kwon do | |
Yoga | |
swimming | |
Kick-boxing |
To simulate the gym classes and estimate the probability that a new gym member will signup for each class, that make a spinner with four segments that represent each percentage of gym members for each corresponding class.
Spin the spinner
Outcome | Frequency |
Tae kwon do | |
Yoga | |
swimming | |
Kick-boxing | |
Total |
Now, divide each frequency in the frequency table to get the probabilities for each outcome.
Outcome | Frequency | Probability |
Tae kwon do | ||
Yoga | ||
swimming | ||
Kick-boxing | ||
Total |
Make a probability histogram by charting probability on the vertical axis and outcomes on the horizontal axis.
Hence, therefore the probability that a gym member signs up for the tae kwon do class is
