Writing a function to calculate scores

[Grace Anne St Clair-Bates]

Hello! I am trying to write a funtion that calculates scores of three random dots on a "bean-bag" board that land on different holes. Each hole holds a certain amount of point. I need to take where the computer has randomly places three points in my turtle graphic and calculate the total score. I have no idea how to do this. Please help if you can! Its really hard to explain it, but if anyone has the slightest idea please let me know. Thanks!
