Probability calculation issue in a spinning wheel Attached herewith is a spinning wheel. It's partitioned to equal 16 pieces and have four colors. Each color has 4 pieces which doesn't have an equal spread. 
That is, 4 green, 4 blue, 4 red and 4 yellow, but placed in different places. 
My problem is, does probability of getting some color is 0.25? (I suppose no)
I personally have a feeling that, there's a high chance of getting red (according to this wheel) as it's spreaded all over the wheel.
Is my conclusion and the reasoning valid? 
Could you please explain if there's any misconception? 

 A: I'd start by ignoring the colors completely and asking: are the 16 slots totally equivalent as possible outcomes? Is there any that is more likely to come out, e.g. because it's bigger or some other slot is heavier or there's a bias in the way the wheel is spun?
If the answer is that the 16 slots are equiprobable, then each can come out with probability $\frac{1}{16}$. As a consequence, each possible group of 4 slots will get four times that probability, i.e. $\frac{1}{4} = 0.25$. Now you can re-add the colors.
Your intuition is that spreading the color in the wheel gives you better chances. But you're not placing guards in a territory, where they get a better view if they are spread evenly: each color still gets the same amount of the wheel.
When I look at the wheel and see those four red sections all alone I get the impression that there's a much higher chance that none of them will be selected. While there seems to be a lot of green there! So perceptions change from person to person, while hopefully the math is the same.
