A proud contributor to the Crusade of Answers -- more info on meta. We are recruiting: just visit the chat room. :)


A mathematics enthusiast caring to help others out. My most knowledgeable areas are logic and category theory. I also know a fair share about measure theory and functional analysis, along with the standard undergraduate curriculum.

When applicable, in the process of answering/helping out, I point people to the community effort ProofWiki which catalogues and rigorously founds proofs in all areas of mathematics.

I am not a native speaker of the English language, but I try to approximate this status; please feel free to point out any errors (perhaps the best way to do so is through chat or e-mail -- see below for the latter).


For those trying to contact me urgently cq. personally, you can direct an email to the following address (all letters lowercase):

It would seem that you double-counted the scenario "7-5 after 5-5". This can be mitigated by passing to 6-6.

I'm voting to close this question as off-topic because OP has been helped and the question carries no value to future visitors.

It would also seem that you tried to write $P(a \mid b) = \sum_c P(a \mid b,c)P(c \mid b)$ (so without the $+$). For some basic information about writing maths on this site see e.g. here, here, here and here.

Hello, welcome to Maths.SE. Thank you for your question! It is good practice on this site to add a bit of information on the context your question came up in, and to share your own work on it. It's also fine if you state that you're completely lost -- the information is helpful for answerers to gauge their answer on. For more information on asking a good question on this site, see here.
