The theoretical (or Laplace) probability of an event E occurring that belongs to a sample space S, in which all events have the same probability of occurrence, is defined in mathematical notation as:P (E) = n (E) / N (S) Where P (E) is the probability, given as the quotient between the total number of

The circular permutations are different types of groupings of all elements of a set, when they are to be arranged in circles. In this type of permutation the order matters and the elements are not repeated. For example, suppose you want to know the number of distinct arrays of digits one through four, placing each

The quasivariance , quasi variance or variance unbiased is a statistical measure of the dispersion of the data in a sample from the mean. The sample, in turn, consists of a series of data taken from a larger universe, called the population . It is denoted in various ways, here s c 2 has been
