On the basis of information it is known that the judgement given by the judge is correct in 90 percent of the cases. Also let us suppose that 40 percent of the cirminals produced befoer court are actually innocent.

Ok I understand up to here but what are the next steps.
Thanks in advance,

Youre welcome. The important question though is: do you know why it is not differentiable at those two points where its not differentiable?
I think the graph has holes on (-1,1).
Am I right?
#39 Re: Help Me ! » Need helpppppppppppp!!!!!!!!!!!!!! » 2007-07-03 21:50:45
Another example:
This one is continuous everywhere and not differentiable at exactly two points (which is what is required).
Oh!! Thanks a lot.:lol:
