Click to expand... Please share your detailed work for part (a) hint for part (b): if F(y) =e^(n*y) \(\displaystyle \frac{dF(y)}{dy} = ?\)................. Parts (a) & (b) of the question are not related. I probably interpreted the problem [part (b)] incorrectly. See response #3 below. Last edited: May 23, 2020
