There is 1 two and 6 total numbers so:
1/6 (16 2/3 %)
No one specified what the definition of "close" is, but I would say a 1 2/3 percent difference is significant if you are going to have many trials
100(3/20-1/6)/(1/6)
600(9-10)/60=-10%
So the experimental probability will wind up predicting 10% less occurrences than the theoretical probability would. That can be quite a difference for a large number of trials. The larger the sample the closer you get to the theoretical probability.
