Hi Everyone!
Could you guys please check my work? And explain to me the ones I left blank, and give me the answer for those so I can further analyze it? I would appreciate that :D

And since this is a New Users forum....HI I'M SPOTTY. AND I LIKE DINOSAURS. AND MUSIC. :)

P.S. Can you guys read that? And if you can't, I suggest dragging it onto your desktop and zooming in or something. if that doesn't work, let me know! D: Because I REALLY need help.

Or just click on it when the little window comes up. :3

Ok it looks like this is all about triangles and areas of a circle, use pythagorus to get sides of triangle, A=pi*r^2 and A=0.5*b*h for areas. At each step ask, what can I work out..... for the probabilities, you need the fractions of shaded to whole - i.e. work out some more areas! Impossible to look at your ans without any working.
