Document Summary

Describes mathematically the outcome of random processes. The sum of the sample has to be 1: event. S = {1,2,3,4,5,6: probability of an event. Calculated by the sum of the of the probabilities of a sample space. Check that the table satisfies probability rules 1 and 2. Rule 1: are the values less than 1. Rule 2: do the values add up to 1. Look at the probability of each of your samples to determine the probability of an event: combination rule. Use probability rule 2 to determine what the probability of each occurrence is. Use combinations formula n!/n! (n-n): equally likely outcomes. Empirically: based on knowledge of previous events.
