comment In primary school I was showed this. Why does it work?
Why does this fail for 645? (or any A,B,C in general?)

comment Ambiguity of notation: $\sin(x)^2$
Your first line holds if it is only about a single variable. However, if x is defined as y+z you could see sin(y+z)^2 meaning sin((y+z)^2)

comment proof by induction - explanation on it
The core point here is that you choose your base case in such a way that the base case is case k for some k. (Often k=1 is chosen here)

revised Define an infinite subset of primes such that the sum of reciprocals converges
Without this edit the uniqueness of choices is not guaranteed. (You need to make sure to pick something below 2^n+1)

comment Safe with $12 \times 10^6$ combinations? How is it possible?
It looks like this safe does not have an 'end of sequence' button. As such a person who wants to try a few codes of length 6, will automatically attempt a number of codes of shorter length. In any case, for reasonable safety I would recommend you to pick a code of at least length 5. Below that a patient person can crack it manually.

comment Average of percentage of 2 numbers.
For completeness, it should still be the weighted mean of the percentages if the prices differ. Just weighted by the sum of prices in each group.

comment Should I throw the dice again if I have rolled 4?
Nice note on the variability. This especially matters if you play something like 'first to five points wins and a tie counts for half'. Then you could choose to play it safe if you are close to winning the match. -- Sidenote, if only a loss gives your opponent a point as well the last line is not relevant.

@TonyK I understand the answer now, if you could edit it I can correct my unjust vote.

@WillieWong Thanks, it was a simple typo, though it goes against my intuition my results now agree with those by TonyK.

Considered downvoting for incompleteness, but then realized it reasonably answers the short version of the third question edit. Would still recomend updating the answer to cover the full question.

comment Should I throw the dice again if I have rolled 4?
It seems like there are now several (valid) different conclusions drawn about the game. Could you specify the rules in more detail? Especially the order in which events happen ( I assumed Player 1 Roll 1, Player 1 Roll 2, Player 2 Roll 1, Player 2 Roll 2)

comment Should I throw the dice again if I have rolled 4?
I am not sure which situation this describes, perhaps the decision to reroll the four made in advance (regardless of the previous rolls).

comment Should I throw the dice again if I have rolled 4?
@TonyK It seems like you consider a different game than me. I consider the situation where the second player already knows the outcome of the first players throw (and uses that information in a smart way).

comment Should I throw the dice again if I have rolled 4?
@SvenB Perhaps I should have formulated it like so: If you roll again, your expected outcome is lower than what you currently have. (Because 4 is an above average roll).
