... Remember: We are dealing with theorectical probability, therefore models are only models. Don't assume everything is normal. Is the normality assumption justified? Does it tell you? Watch out for variables that are not independent. Does one depend on the other? Variances add, Standard deviations ...

... Given n numbers in [0, 1] can we approximate the median via sampling? This will be part of your homework. Exercise: Show that it is impossible to estimate the value of the median within say 1.1 factor with o(n) samples. But what is possible is to produce a number that is an approximate median: it is ...

Fisher–Yates shuffle
The Fisher–Yates shuffle (named after Ronald Fisher and Frank Yates), also known as the Knuth shuffle (after Donald Knuth), is an algorithm for generating a random permutation of a finite set—in plain terms, for randomly shuffling the set. A variant of the Fisher–Yates shuffle, known as Sattolo's algorithm, may be used to generate random cyclic permutations of length n instead. The Fisher–Yates shuffle is unbiased, so that every permutation is equally likely. The modern version of the algorithm is also rather efficient, requiring only time proportional to the number of items being shuffled and no additional storage space.Fisher–Yates shuffling is similar to randomly picking numbered tickets (combinatorics: distinguishable objects) out of a hat without replacement until there are none left.
