Is RandBetween truly random?
While the RAND() RandBetween() and now RandArray() functions in Excel are sufficiently ‘random’ or pseudo-random for most purposes there are situations where it isn’t really enough. You might want truly random numbers, not those generated by a mathematical formula like that in Excel.
How random is pseudorandom?
Software-generated random numbers only are pseudorandom. They are not truly random because the computer uses an algorithm based on a distribution, and are not secure because they rely on deterministic, predictable algorithms.
Is it possible to generate truly random number sequences?
Yes, you can generate truly random number sequences. But you can’t do it with a computer’s random number generator, which uses some very nice formulae to generate pseudorandom numbers. Here are two basic ways to generate truly random number sequences. Find some process in the world that is chaotic.
Is there such a thing as random numbers?
There is a sense of a particular number being random from Kolmogorov complexity, but that is not what is intended here. Instead, what we are interested in might be called a random process- a process that generates a sequence of numbers so that the sequence satisfies some particular probability distribution.
Is it possible for the brain to generate random numbers?
While behavioral output is almost always meaningful in some way, the actual activity of the components of the brain (neurons, brain waves) is sufficiently unpredictable that it could be used to generate random numbers. If you listen to the sound of a single spiking neuron, it sounds like a geiger counter.
Why can’t I generate random numbers from a time stamp?
Because You need to write code to generates the random numbers and Code is NOT random. (It’s deterministic) So you wind up starting with a “Seed value (s)” that is picked at “Random” (usually the current time stamp) then use it in an algorithm to start generating numbers.
