 Mar 19 comment How to prove that $\sum_{d|n}d^{-\varepsilon}\leq C(\varepsilon)n^{\varepsilon}$ This is true even for $\epsilon=0$. Mar 19 comment Please Help me. (Poisson Process: Customer arrival time). Just noticed that this could be done easier if we ignore the order between $S_i$'s and regard them as the independent uniform random variables on $[0,t]$. Mar 18 answered $P(\{S_k\ge c\}\cap\{S_{k-1} 2Y)$? The answer turns out to be $(2015-411\sqrt{17})/1536\approx 0.2086$. Mar 18 comment Let $X = \dfrac{1}{25} \sum\limits_{i=1}^{25} X_i$ and $Y =\dfrac{5}{2}X - \dfrac{2}{5}$. What is $P(|Y| > 1)$? The numerical value is approximately 0.8653.
