Fundamental Counting Principle´Fundamental Counting Principle:ÖIf an event M can occur in m ways and is followed by an event N that can occur in n ways, then event M followed by event N can occur in Öm n ways. independent eventsyindependent events:ÖTwo or more events in which the outcome of one event does not affect the outcome of the other events.  outcomekoutcome:ÖOne possible result of a probability event.ÖExample: 4 is an outcome when a number cube is rolled.   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. P(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. simple random sampletsimple random sample:ÖA sample where each item or person in the population is as likely to be chosen as any other.  stratified random sample©stratified random sample:ÖA sample in which the population is first divided into similar, nonoverlapping groups; a simple random sample is then selected from each group. systematic random sample€systematic random sample:ÖA sample in which the items in the sample are selected according to a specified time or item interval. 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. unbiased sampleaunbiased sample:ÖA sample that is selected so that it is representative of the entire population. voluntary response sampleUvoluntary response sample:ÖA sample that involves only those who want to participate.ñê
