Galton Box Probability

i goes as high as the number of balls. arrayslots is as big as the number of slots. But you make reference to arrayslots[i], so if the number of balls exceeds the number of slots you will get this error.

You should probably be referencing arrayslots[j] instead.

PHP Random Probability
That will work (with one caveat), although I would still recommend using mt_rand instead of rand. The main difference is that mt_rand uses a different PRNG (pseudorandom number generator) engine that generally provides results that have better randomness than rand. Even so, this method has an issue, which you may or may not consider severe. The potential issue comes from the floating point repres

Matlab Conditional probability from dataset
Sine your code didn't work by copy & paste, I changed it a little bit, It's better if you define a function that calculates the probability for given data, function p = prob(data) n = size(data,1); uniquedata = unique(data); p = zeros(length(uniquedata),2); p(:,2) = uniquedata; for i = 1 : size(uniquedata,1) p(i,1) = sum(data == uniquedata(i)) / n; end end Now in another script, data

Generate N "random" string of length K using probability table
I'm sure there is a cleaner/better way, but here is one easy way to do this. Here we're filling pick_list with the 100 separate character-pair values, the number of values determined by the probability. In this case, there are 20 'aa', 30 'ab' and 50 'ac' entries within pick_list. Then random.choice(pick_list) uniformly pulls a random entry from the list. import random prob_table = {'aa': 0.2

My android app crashes with low probability when it call system gallery to open image
Do you think this is happening because you are getting a URL instead and not a local image location? something like getting a picture from Dropbox or Google drive. If this is the case then probably you can try this, if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true); } Or handle the URL in some other way which is something I have
