Answer:
2.8 putts in average on any given green
Step-by-step explanation:
To calculate how many putts Madison will need on any given green, we need to calculate the weighted average of his putts.
We use a global sample of 100 puts and factor in the fact he had a one-putt performance 15% of the time, two-putts 20% of the time and so on.
So, the calculation goes like this:
[tex]\frac{1 * 15 + 2 * 20 + 3 * 35 + 4 * 30}{100} = \frac{280}{100} = 2.8[/tex]
So, he'll need an average of 2.8 putts in average on any given green.
Which makes sense since 65% of the time, he needs 3 putts or more on the green.
