A spinner is separated into 5 equal pieces, as shown below:

A spinner is shown with five colors, brown, blue, purple, orange and red marked on it. The arrow points towards the brown color.

Patrick spins the spinner 9 times. What is the theoretical probability that it stops on the brown sector on the last spin?

1 over 45
1 over 25
1 over 9
1 over 5

as a major hint, the spins are independent events, meaning the last spin is unaffected by the previous outcomes. therefore, you simply have to determine

(# of desired outcomes) / (total outcomes) for one spin
