what is a graphical representation of a frequency distribution?
Histogram . A probability distribution is a mathematical description of the probabilities of events, subsets of the sample space.The sample space, often denoted by , is the set of all possible outcomes of a random phenomenon being observed; it may be any set: a set of real numbers, a set of vectors, a set of arbitrary non-numerical values, etc.For example, the sample space of a coin flip would be Ω . It is used in many academic and professional disciplines but most widely so in the fields of mathematics, medicine and the sciences.
