At the school carnival, Maya is playing a game called "Color Spin." The game uses a large spinner divided into 8 equal-sized sections:
- 3 sections are Blue
- 2 sections are Red
- 2 sections are Green
- 1 section is Gold
If Maya spins the spinner 40 times, how many times would you expect her to land on a Green section?
10 times
