comment Subtraction Game
For odd $k$ the position is very simple: is $N$ odd or even?. For even $k$, there are a couple of layers of complexity.

comment Finding the required volume and measurements of a storage container
The total volume is $280$ times the individual volumes, which are the product of the three sides. The dimensions of the big container depend on how you stack the small containers.

comment If $ P(A) = 0 $ is $ A $ a null event?
I am not sure "$P(X=1/2)=0\quad\mbox{a.s.}$" is a good example of using "almost surely". An alternative might be to say "$X$ is not $2$ and $X$ is almost surely not $\frac12$. Though both events have probability zero, the first is impossible while the second is only improbable."

Perhaps it may be suggesting that the additive inverse of $x$ is $-x$. Or perhaps not.

What makes you think that might work? And what does it have to do with statistics?
