Title: The n Dice on the floor. All points of the dice on the upward side and one s. Enter n, the probability of printing s all possible values.Statement ideas are not original!

instructions: A dice have n-sided, each side has a different number a[i], and give a m, give M face, these faces if the dice to, you can continue to dice once, ask you sic once get the number of expectations is how much? problem-solving ideas: I started to push the formula, but due to the wrong way of thinking, calculate a bit of trouble, in fact, the transforma

How can I continue to throw at least?Problem Extension: If I have four things, five things, eight things, nine things, ten things ...... How can I use n cases?Minimum throwing timesTo achieveUniform Distribution? From:The problem comes from Ideas: Note the keywords in the problem:

Points of n dice. Place n dice on the ground, and the sum of all dice toward the point above is S. Input n to print the probability of all possible values of S. Thought: F (N, S) = f (n-1, S-6) + f (n-1, S-5) + f (n-1, S-4) + f (n-1, S-3) + f (n-1, S-2) + f (n-1, s-1 ); # Include

N faces of the dice to obtain the expected value of each face at least onceSet DP [I] to the expected values that have already been thrown into different interfaces DP [N] = 0 evaluate DP [0]Because DP [I] still needs to throw I different faces. Each time, it may throw a face that has already been thrown or a face that has not been thrown to it.So DP [I] = (I/n) * DP [I] + (n-I) /n * DP [I + 1] + 1 equal sign 2 side has DP [I]DP [I] = DP [I + 1] + N/(

ArticleDirectory Yangche Problems Bayesian inference Yangche Problems The Monty Hall problem, also known as Monti Hall, is a famous probability problem. It originated from a video game: If you are a contestant in a game, there are three closed doors in front of you. One is behind a car, and the other two are behind goats. The host know

This article mainly introduces Python's use of the random and tertools modules to solve some classic probability problems. This article describes the use of the random and tertools modules to solve the problems of goat door, playing cards, and birthday paradox, for more information, see Common functions in the random module The code is as follows: Random ()Retur

Test instructions: In ACM Contest, the n question, the T team. Give each team the probability of doing each question, ask each team at least one question, at least one team to do at least the probability of the M problemAnalysis: dp,f[i][j] indicates the probability of the first team doing the question J.

Python uses the random and tertools modules to solve some typical Probability Problems. Common functions in the random ModuleCopy codeThe Code is as follows:Random ()Returns a real number within the range [0, 1;Uniform (a, B)Returns a real number in the range [a, B;Randint (a, B)Returns an integer in the range [a, B;Choice (sequence)Returns an element in the sequence. The sequence is an ordered sequence, su

The probability of the first K-card to the k+1 position is also equal.The Bayesian formula, the conditional probability, is needed here.What we are asking here is actually the probability of the index of any one of the previous K-cards x to the first K-position, if equal to
