I'm broadly interested in very applied math. I try to apply ideas from mathematics, statistics, machine learning, formal systems and computer science to solve real-world problems. Mostly in applied finance/quantitative trading, but in other areas if the mood takes me.


The following is for my own use, but feel free to borrow it -

Hi. It looks like you are new here. We are generally very willing to help, but we like users to show the work that they've done towards solving the problem on their own first. If you can edit your question to show the code you've written so far, and where you are stuck, then you will get a much better response.

comment A fair coin is flipped 2k times. What is the probability that it comes up tails more often than it comes up heads?
It seems likely that the "2k" in the question refers to a general even number $2k$ rather than "2000".

comment Help with 2 questions my professor gave us
For (i) assume there are two solutions $a,b$ s.t. $a^2=r$ and $b^2=r$ with $a\neq b$. Then either $a>b$ or $a<b$. Can you derive a contradiction?
