This is my go-to "weighted" random, where I use an inverse function of "x" (where x is a random between min and max) to generate a weighted result, where the minimum is the most heavy element, and the maximum the lightest (least chances of getting the result). Or maybe there are some ready gems on Ruby? But apple should be picked 4 times as frequent as Lemon and 2 times as frequent as orange. Does JavaScript have a method like "range()" to generate a range within the supplied bounds? You need to know how it works under the hood and it will be great if you can implement it by yourself. Huge value and great work. For example, if you have the weights for. We can just generate a random integer between 1 and 10 firstly, then return a letter based on this number: The above code avoids generating a list like the previous solution, so it's more efficient. The perfect solution to make some test data look a bit more convincing in graphs. =index (A2:A,randbetween (1,counta (A2:A))) Range A2:A should contain your list of names. I appreciate your generosity. The RNG algorithm is cryptographically safe, results in an unbiased pick, and can be used instead of a coin, dice, or another more primitive randomizing device (which might actually be biased due to imperfect construction). Simply enter all names, say 22 for football (soccer), and tell the tool to select 11 names. Column C contains the probability weight assigned to each number, entered as a percentage.
