4. because it is reduced and the simplest to understand
Well this is a more complicated question than it may seem.
The laws of probability are based on observations whose number is very large or actually as the number of observations approaches infinity.
So on the one hand, you should be concerned that you get 0/8 to land on 3.
However, 42/500 land on 3 so your ratio has improved.
It's not near 125 but it's also not 0.
If it remained at 0, you would begin to be concerned and rightly so.
Perhaps if you did 5000, you would be less concerned as the ratio improved and got closer to 1/4 of the observations.
So at this point I don't think you have enough information to determine that the spinner is unfair.
To solve this kind of problems you would do
Is/of and %/100
To solbve you would multiple the two numbers diagonal from each other and divide by the remaining number. So you would do 27 multiplied by 100 divided by 32 to get your answer.
