Answer:
![P(x \le 10) = 0.85](https://tex.z-dn.net/?f=P%28x%20%5Cle%2010%29%20%3D%200.85)
Step-by-step explanation:
Given
See attachment for properly presented question
Required
![P(x \le 10)](https://tex.z-dn.net/?f=P%28x%20%5Cle%2010%29)
From the question, we understand that he takes 40 shots (trials)
So:
![n = 40](https://tex.z-dn.net/?f=n%20%3D%2040)
From the attached plot, the number of attempts up to the 10th is:
![x \le 10 = 9+6+5+4+4+2+2+0+1+1](https://tex.z-dn.net/?f=x%20%5Cle%2010%20%3D%209%2B6%2B5%2B4%2B4%2B2%2B2%2B0%2B1%2B1)
![x \le 10 = 34](https://tex.z-dn.net/?f=x%20%5Cle%2010%20%3D%2034)
So, we have:
![P(x \le 10) = \frac{n(x \le 10)}{n}](https://tex.z-dn.net/?f=P%28x%20%5Cle%2010%29%20%3D%20%5Cfrac%7Bn%28x%20%5Cle%2010%29%7D%7Bn%7D)
![P(x \le 10) = \frac{34}{40}](https://tex.z-dn.net/?f=P%28x%20%5Cle%2010%29%20%3D%20%5Cfrac%7B34%7D%7B40%7D)
![P(x \le 10) = 0.85](https://tex.z-dn.net/?f=P%28x%20%5Cle%2010%29%20%3D%200.85)
