The sum of the probabilities of complementary events is 1. fundamental counting principle¬fundamental counting principle:ÖUses multiplication of the number of ways each event in an experiment can occur to find the number of possible outcomes in a sample space.  percent\percent:ÖA ratio that compares a number to 100.ÖExample:Ö76 out of 100 isÖ76 percent or 76%.  populationVpopulation:ÖA large group of data from which a sample of statistical data is selected.  probabilityÅprobability:ÖThe ratio of the number of favorable outcomes for an event to the number of possible outcomes of the event.ÖP(a) = (number of favorable outcomes) / (total number of possible outcomes). randomLrandom:ÖOutcomes occur at random if each outcome is equally likely to occur. sampleHsample:ÖSome portion of a larger group selected to represent that group.   sample space=sample space:ÖThe list of all possible outcomes for an event.  surveycsurvey :ÖA question or set of questions designed to collect data about a specific group of people.Ö  theoretical probabilityptheoretical probability:ÖThe ratio of the number of favorable outcomes to the total number of possible outcomes.   tree diagramWtree diagram:ÖA diagram used to show the total number of possible outcomes of an event.V9
