The kong vong toch ( Khmer: គងវង់តូច or kong touch Khmer: គងតូច) is a number of gongs that are attached to a circle-shaped rack, closely resembling its larger relative, the kong thom. Both instruments belong to the percussion family of traditional Khmer instruments, along with the roneat ek, roneat dek, and roneat thung.
The indigenous Mon-Khmer minority known as Khmer Ler, who are called those khmer living in higher latitude land only, inhabited Northeastern Cambodia and other mountainous region in mainland Southeast Asia popularly dance circling the campfire at night. This dancing (romvong) dates for millenniums. In the Leang Arak rituals or Lerng Nak Ta ...
The cumulative distribution function of a real-valued random variable is the function given by [ 2]: p. 77. (Eq.1) where the right-hand side represents the probability that the random variable takes on a value less than or equal to . The probability that lies in the semi-closed interval , where , is therefore [ 2]: p. 84.

In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a given point in space is specified by three real numbers: the radial distance r along the radial line connecting the point to the fixed point of origin; the polar angle θ between the radial line and a polar axis; and the ...
In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. Thus, if the random variable X is log-normally distributed, then Y = ln (X) has a normal distribution. [ 2][ 3] Equivalently, if Y has a normal distribution, then the exponential ...
A random variable (also called random quantity, aleatory variable, or stochastic variable) is a mathematical formalization of a quantity or object which depends on random events. [ 1] The term 'random variable' in its mathematical definition refers to neither randomness nor variability [ 2] but instead is a mathematical function in which.
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
