comment Limit of: $\lim_{x\rightarrow\infty}\left(\dfrac{x+2}{x+1}\right)^{x/2}$
Jumped way too many steps with the last equality, even with the comment. Given that the OP asked this question, I am pretty convinced he could not have filled all these gaps himself.

still not convinced, you are saying $\lim a^b = (\lim a)^{(\lim b)}$. Your supposedly justification does not do the job.

Not convinced by the last equality.

(2) and (4) are the same is my feeling too, thank you. I would like to have another confirmation before accepting this.

comment Binomial/Poisson distribution question
@Henry i am sorry, i am asking about (ii). I do not understand how it is different to (iv), maybe it is not. I would like an independent confirmation. I was meant to say 1,3,4 are easy...

comment Normal distribution tail probability inequality
so your approach is valid for $t\geq \sqrt{\pi/2}$. i do not know how to do it, so maybe, you start by assuming otherwise.

Hi Sadegh. Please show us what you tried so far by editting the question. As it stands, this question fails to meet the quality of questions expected on this site.

Because $P_{12}$ is prob from state 1 to 2, not vice versa
