Hi, I was hoping there are some older kids who can help me with this for online school. I don't understand probability, how can you predict something if all of the sides are equal? If there is a blue square a red square, and green square that are the same size how will I predict what the spinner will choose. Thanks.

So let’s use your example. If there are three equal different coloured sections, with an equal chance you will land on each, it’s a one-in-three chance of landing on any section.

If there are (let’s say) eight equal sections, but there are three blue bits, two red bits, two yellow bits and one green bit, the chance of you landing on a blue bit is three-in-eight, and landing on a red bit is two-in-eight, or one-in-four (always round to the simplest form). Does that make sense?

Hope this helps! :D

If there is one blue, one red, and one green that are all the same size then you have a 1/3 of picking blue, 1/3 red and 1/3 green. If you need percentage it is approximately 33% of any of them. You can't predict it exactly if everything has the same chance, you can say how likely it is that it will be picked, as in if it is likely, unlikely, certain, impossible or none of the above. 33% I think is neither likely nor unlikely,.
