Let\'s say I have a list开发者_高级运维 in python with several strings in it.I do not know the size.How can I run a loop to do an operation on 2 random elements of this string?
what is the best approach to generate random samples from bivariate normal and student T distributions? In both cases sigma is one, mean 0 - so the only parameter I am really interested in is cor开发者
For a list of 10 ints, there are 10! possible orders or permutations.Why does random.shuffle give duplicates after only 5000 tries?
This problem is a little similar to that solved by reservoir sampling, but not the same.I think its also a rather interesting problem.
You have a biased random number generator that produces a 1 with a probability p and 0 with a probability (1-p). You do not know the value o开发者_如何转开发f p. Using this make an unbiased random num
I\'ve been asked (as part of homework) to design a Java program that does the following: Basically there are 3 cards:
We\'ve all poked fun at the \'X minutes remaining\' dialog which seems to be too simplistic, but how can we improve it?
I need to calculate the probability mass function, and cumulative distribution function, of the开发者_高级运维 binomial distribution. I would like to use MATLAB to do this (raw MATLAB, no toolboxes).
Given a set of 100 different strings of equal length, how can you quantify the probability that a SHA1 d开发者_如何学运维igest collision for the strings is unlikely... ?
I\'m coding a board game where there is a bag of possible pieces. Each turn, players remove randomly selected pieces from the bag according to certain rules.
