A - 60% of the serves were in bounds, B - while 40% were not in bounds.
A - To find the percentage of serves that were in bounds, you can use the formula:
Percentage in bounds = (Number of serves in bounds / Total number of serves) * 100
In this case, the number of serves in bounds is 0.6 times 15 (since 0.6 of the first 15 serves were in bounds), and the total number of serves is 15.
Percentage in bounds = (0.6 * 15 / 15) * 100
Percentage in bounds = (0.6 * 100)
Percentage in bounds = 60%
So, 60% of the serves were in bounds.
B - To find the percentage of serves that were not in bounds, you can subtract the percentage in bounds from 100%:
Percentage not in bounds = 100% - Percentage in bounds
Percentage not in bounds = 100% - 60%
Percentage not in bounds = 40%
So, 40% of the serves were not in bounds.
