NMAI069 (Mathematical skills) - just set theory nothing much of note.. next week we have a quiz

NDMI002 (Discrete mathematics) [lecture] - probability, defined the random variable and expected value of a random variable, trivial proof of linearity of expectation.. then markov's inequality, only used to prove chebyshev's inequality we'll see what use that has sometime else

NDMI002 (Discrete mathematics) [tutorial] - a quiz that i've made a small mistake on and also didn't write out that well, some problems on probability including the classic 20 people who don't share a birthday problem but also others like electronics with a fixed chance of being broken and sex assigned at birth, all pretty simple things

no NMAI069 today because i was at the psychiatrist in the morning and when i arrived i didn't want to show up for just the end of the class

NDMI002 (Discrete mathematics) [lecture] - problem of a cloakroom attendant which in other words is the probability of a permutation to have no anchors (elements that permute onto oneself).. as the amount of things permuted nears infinity the probability approaches e^-1, with that we ended combinatorics and started with probability we had an example of a disease test with a specific probability of not working out that lead to the introduction of bayes' theorem

NDMI002 (Discrete mathematics) [tutorial] - had a quiz which i failed... after the quiz we had some examples of using the inclusion exclusion principle including counting the amount of surjective functions from and to a finite set!

NPRG062 (Introduction to algorithms) [tutorial] - went over homework regarding big o of various functions and grouping them based on when they share the big o, that was it

NPRG030 (Programming 1) [tutorial] - i programmed newton method for approximating a function for any polynomial(!) homework is writing a polynomial calculator for addition, multiplication and division

NJAZ070 (English for Upper-Intermediate Students I) - no english mathematics today, just focusing on exercises from the book, some to do with tenses of the past and some about vocabulary, homework was reading an article about mobile phones from the book and answering some questions, one guy in the class was dressed as mario cause it's almost halloween and he was going to some hockey game later to day with friends and they were all dressed up for halloween i think

another three hour block of no classes, went to ikea this time walked around for a bit looking at all the furniture and stuff it was rather interesting, then ate falafel, in the end i ended up buying the funny rat, gosig råtta

NMSA230 (Introduction to R programming) - the entire class was dedicated to probability functions both discrete and continuous and how to work with them, i have no background in any statistics so i'll have to learn those things on my own time
