The probability that a 7th grader selected will play guitar.
From the attachment, we have:
![7th\ graders =11+8+8+13](https://tex.z-dn.net/?f=7th%5C%20graders%20%3D11%2B8%2B8%2B13)
![7th\ graders =40](https://tex.z-dn.net/?f=7th%5C%20graders%20%3D40)
7th graders that can play guitars are:
![Guitars = 11](https://tex.z-dn.net/?f=Guitars%20%3D%2011)
So, the probability is:
![Probability = \frac{Guitars}{7th\ graders}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7BGuitars%7D%7B7th%5C%20graders%7D)
![Probability = \frac{11}{40}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B11%7D%7B40%7D)
