Are there General methods to distinguish a coded message from the noise?

An important indicator of the quality of encryption algorithms and hash is a uniform probability distribution of the output posledovatelnosti. Suppose we obtained data possibly as a coded message by an unknown arbitrary code. Are there any reliable methods allowing to solve are data of sense or are white noise? What to read...

What is wrong with this coin?

Once at the interview I was asked the following problem: there is a curve of the coin, the eagle falls with a probability of 0.49, and tails with a probability of 0.51, as using a coin to hold a fair draw, that is, to two events, whose probability is the same. I'm certainly not an expert in the field, but the decision was c...

How many rounds happen before the series of n failures?

There is a gap of numbers from 0 to 99.99. Of this period, selects a series of numbers. The program generates each iteration a random number from the first interval. How to calculate how many hits the target number will be (on average), until a series of n failures? The formula should take a chance on success (that is, if t...

How to derive a suitable formula for the distribution of the probabilities?

Hello! I rewrote this question short. I need to calculate the probability of occurrence of the event (first calculate the probability table with the events, then use it to calculate which event is now dropped). The columns I wrote – it's just a table of distribution the probability of (occurrence) of the event. Example: 65...

How precisely to predict the combination?

Good day! There is a game with a run of 8 digits (each from 0 to 99). Ie times drop 8 different numbers, for example: 8, 91, 17, 25, 42, 31, 98, 65. I have an array with 500 such wymaganiami. As best you can predict what numbers will come out? The most logical and the first thing that comes to mind is to calculate what com...
