機率密度函數- 维基百科，自由的百科全书 概率密度函数一般以小写“pdf”（Probability Density Function）標记。 概率密度函数有时也被称为概率分布函数，但这种称法可能会和累积分布函数或概率质量函数混淆 ...
Probability Function -- from Wolfram MathWorld The probability function P(x) (also called the probability density function (PDF) or density function) of a continuous distribution is defined as the derivative of the (cumulative) distribution function D(x),D^'(x)=[P(x)]_(-infty)^x(1)=P(x)-P(-infty)(2)=P

Probability Density Function -- from Wolfram MathWorld The probability density function (PDF) P(x) of a continuous distribution is defined as the derivative of the (cumulative) distribution function D(x), D^'(x) = [P(x)]_(-infty)^x (1) = P(x)-P(-infty) (2) = P(x), (3) so D(x) = P(X
Probability density function - Wikipedia, the free encyclopedia In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function that describes the relative likelihood for this random variable to take on a given value. The probability of the random variable falling
Probability amplitude - Wikipedia, the free encyclopedia In quantum mechanics, a probability amplitude is a complex number used in describing the behaviour of systems. The modulus squared of this quantity represents a probability or probability density. Probability amplitudes provide a relationship between the
2. Probability Density Functions and the Uniform Distribution Example 3 Spinning a Dial Suppose that you spin the dial shown in the figure so that it comes to rest at a random position. Model this with a suitable probability density function, and use it to find the probability that the dial will land somewhere betwe

I have a hard time wrapping my head around infinity (probably not the first one.) I get the concept of continuity and that the probability on a specific point is zero.
