PHP winning probability algorithm, winning probability algorithm We first completed the background PHP process, the main work of PHP is responsible for the allocation of prizes and the corresponding probability of winning, the current page click to flip a block will want to background PHP to send AJAX requests, then the background PHP based on the

variables can be listed at most, the random variables are called discrete random variables. 2. Distribution law of discrete random variables (1) Definition: All possible values of discrete random variables and the probability value when taking each value, called discrete random variable distribution law, expressed as Or in a tabular representation: X1 X2 ... xn ... Pk P1 P2 ... pn ... or recorded as ~ (2) Nature:, Note: This property is a suffici

distribution of random variables, is called a finite pair or an infinite set of two-dimensional random variables. The distribution function of two-dimensional discrete random variables is: 5, for a two-dimensional random variable distribution function, if there is a nonnegative integrable function for any real number has is called a continuous two-dimensional random variable, a function called the probability density of a two-dimensional random vari

2.1 Probability density function2.1.1 DefinitionSet P (x) as the probability density function of the random variable x in the interval [a, b], p (x) is a nonnegative function and satisfiesNote the difference between probability and probability density function.Probability is the area of the corresponding area under the

We still use the "Student Network" as a sample, 1.Figure 1First, the intuitive interpretation of causal judgment (causal reasoning) is given.To figure it out.That is, the probability of a student getting a good recommendation is about 0.5.But suppose we know that students have a lower IQ. Then the probability of getting a good letter of recommendation is reduced:Further. Assuming that the exam is very diffi
