O produto aleatório de variáveis aleatórias

Abstract

Throughout history, much has been studied about the algebra of random variables. From addition to division, there are countless texts that analyze, elucidate and describe discoveries that are very important for the advancement of science. Among these subjects, the product of random variables was always lower in the number of publications item. Until the mid-twentieth century, still unpublished findings of formulas about this type of problem, although some authors have already made discoveries that lead all researchers who sent after. With this, the objective of the work is analyzed and understood as characteristics that vary according to the variables, from a historical review on the product to a review of the results obtained on the random product, being its probability and variance. Therefore, it is intended to contribute a little more to the scientific field and start to break new ground in an area that is very interesting and promising.
