      n   pl   , -ties  
1    the condition of being probable  
2    an event or other thing that is probable  
3      (Statistics)   a measure or estimate of the degree of confidence one may have in the occurrence of an event, measured on a scale from zero (impossibility) to one (certainty). It may be defined as the proportion of favourable outcomes to the total number of possibilities if these are indifferent (mathematical probability), or the proportion observed in a sample (empirical probability), or the limit of this as the sample size tends to infinity (relative frequency), or by more subjective criteria (subjective probability)  

classical probability  
      n      another name for       mathematical probability  
conditional probability  
      n     (Statistics)   the probability of one event, A, occurring given that another, B, is already known to have occurred: written P(A/B) and equal to P(A and B)/P(B)  
marginal probability  
      n     (Statistics)   (in a multivariate distribution) the probability of one variable taking a specific value irrespective of the values of the others  
mathematical probability  
      n     (Statistics)  
1    the probability of an event consisting of n out of m possible equally likely occurrences, defined to be n/m  
   See also       principle of indifference  
2    the study of such probabilities,   (Also called)    classical probability  
posterior probability  
      n     (Statistics)   the probability assigned to some parameter or to an event on the basis of its observed frequency in a sample, and calculated from a prior probability by Bayes' theorem  
   Compare       prior probability

prior probability  
      n     (Statistics)   the probability assigned to a parameter or to an event in advance of any empirical evidence, often subjectively or on the assumption of the principle of indifference  
   Compare       posterior probability  
probability density function  
      n     (Statistics)   a function representing the relative distribution of frequency of a continuous random variable from which parameters such as its mean and variance can be derived and having the property that its integral from a to b is the probability that the variable lies in this interval. Its graph is the limiting case of a histogram as the amount of data increases and the class intervals decrease in size,   (Also called)    density function      Compare       cumulative distribution function       frequency distribution  
probability function  
      n     (Statistics)   the function the values of which are probabilities of the distinct outcomes of a discrete random variable
