comment Can a function $f:[0,2\pi] \rightarrow 1$ have a PDF and CDF?
@StanShunpike not sure domain of what you are asking about. If domain of $f$ it wouldn't change much...

comment O(n) of given code
@user3904534 the intuition for what you were asking is simple. Note that $$\sum_{i=1}^n 1 = \Theta(n), \sum i = \Theta(n^2), \sum i^2 = \Theta(n^3) \ldots$$

@user3904534 it is irrelevant now, see the updated version.

comment Can a function $f:[0,2\pi] \rightarrow 1$ have a PDF and CDF?
@StanShunpike it means you cannot construct the CDF :), because $Y$ is not a valid random variable. You are right, if is was on any interval of length $1$, e.g. $[0,1]$ or possibly $[\pi, \pi+1]$, it would work just fine :).

comment Finding the no. of non-negative integral solutions to $x+y+2z=33$.
Yes, note that $(x,y,z) = (24.75,0,0)$ solves $x+y+z=24.75$ but not $x+y+2z=33$. Similarly, $(33,0,0)$ will solve the second one but not the first one. They have a different solution space.

comment Law of large number in the proof of linearity of expectation
i think the sum of individual means approaches the mean of the sum...

i don't think simulation is the way to prove linearity of expectation.
