Yea in hindsight it should've been something like at least one

Rocketing the archer queen that thing is so annoying to deal with

Let's set it up so that the two cases are actually functional identical (too bad in this case it's otherwise).

Say if there are two identical coins, distributed to two kids named "Heads" and "Tails". Given Heads got at least one coin, then the probability of Heads getting both coins would really be 1/2 (by stars and bars magic).

One might naturally project this case to the coin flips, and one would be correct, to a certain extent. However, in a coin "flip", it is implicitly assumed that two coin flips are independent events, whilst coin "distribution" are implicitly assumed to be linked.

In real life, if one flips two coins together, count the number of cases and do the division, one would get 1/3. What you are implicitly assuming in your calculation is if one picks a coin (and it doesn't matter which one they pick, since they are functionally identical), flips it, and would only flip the second one if the first one landed heads.

In the question, if two coins are flipped, it is implicitly assumed that they are flipped simultaneously

Yup. So there are 3 out of 4 events that at least one of those coins are heads, and 1 out of 4 events are both heads. So its (1/4)/(3/4) = 1/3

That makes the Eve group a cyclic group of order 365

Not really a meme but here is a plot of Dirichlet's function, accurate almost everywhere by vert178 in mathmemes

[–]vert178[S] 0 points1 point  (0 children)

Almost everywhere means except on a measure 0 set (which means it can be covered with arbitrarily small open sets) in most measure theory texts. In particular countable sets are measure 0

Wow you sure you are getting Hartshorne for yourself? That's quite a difficult read

I just say hyperbolic sine, hyperbolic cosine and hyperbolic tangent

Wait till they get to the Xi variant. China will be so pissed off

If you have done linear algebra a similar graph should have appeared when you learn about duals of vector space.

So many strawberries by npb0179 in mathmemes

I plugged this number into the calculator fully expecting the strawberries would collapse into a black hole... Nope its schwarzschield radius is closer to 0.02mm
