From what I have read, I need to solve Mr F says: No. Solve .
In this case, I have Mr F says: No. Solve
I end up with 0.91267
Not sure that I am on the right track, some guidence would be great
Thank you
You should also sketch a graph of the pdf to see what's happening (it will be clear by the way that m > 0). It would then be clear that your answer looks much too big.
For the next part note that and you should know how to calculate E(Y) when given the pdf.
