comment Limit of a Function: $ \lim_{x \to 0}\ (e^x + x)^ {\large \frac {1} {x}}$
This doesn't convince me.

comment maximising the frequency of mode.
What do you mean by "distribute"? And what does "(give $2$ to $3$)" mean?

comment How does one prove (A - B) - C ⊆ (A - C) - (B - C)
Take an element in the LHS and prove it must be in the RHS.

You can't write the log-likelihood like this. Take a look at your likelihood function instead. Which value of $\theta$ would maximize this function?

comment Method of Moments on a Uniform distribution (a,b)
Your second moment equation is wrong. The right-hand side is the population second moment, the left-hand side should be the sample second moment which is $\frac{1}{n}\sum_{i=1}^{n}x_i^2$.

comment $u$~$N(0,A)$ and z$|u$~$N(u,1)$ how to show that $u|z$~$N(Bz,B)$ where $B=A/(A+1)$?
@Qbik There is no $p(z)$ involved here. You only need the conditional distribution of $p(z|\mu)$.
