Goodness of Fit Test

I have been observing the roulette wheel and I was wondering if the results were consistent with the expected results if all numbers were equally likely.  

 

Outcome

1st 12   1 - 12

2nd 12   13 -24

3rd 12   25 -36

0 or 00

Observed Count

46

52

43

2

Expected %

12/38 = 31.58%

12/38 = 31.58%

12/38 = 31.58%

2/38 = 5.26%

 

  1. How would I go about assessing if my distribution follows the expected or is statistically different than expected? 
  2. If you can, conduct a goodness of fit test and write a narrative summary of your results.
