This could go in the homework section I suppose, but I couldn't follow the guidelines, so I'll try asking it here.
The attached image is a probability distribution for measured fibre angles from a spray up carbon fibre process. This is in a report that I need to explain. To get the probability distributions on the Y axis, would one just add up all the fibres, and divide that total by the number between a given orientation?

I'm asking how would generate the probabilities on the Yaxis?

I know it does, what I'm asking is how was it obtained in the first place? Would you just add up the number of fibres between a certain angle and then divide by the total number of fibres? And that gives probability?

It's generated by looking at all the fibres, putting each one into a category (of orientation), and counting up how many fibres are in each category; then expressing that number as a proportion of the total number of fibres.
This should have been posted in homework help.

Yes, that's what I thought, thanks for your help, maybe it can be moved?
