Document Summary
The probability of any outcome of a random phenomenon is a number between 0 and 1 that describes the proportion of times the outcome would occur in a very long series of repetitions. Probability model- for a random phenomenon describes all the possible outcomes and says how to assign probabilities to any collection of outcomes. We something call a collection of outcomes an event. Personal probability- a personal probability of an outcome is a number between 0 and 1 that expresses an individuals judgment of how likely the outcome is. Any probability is a number between 0 and 1 ( 0 p(c) 1 ) All possible outcomes together must have probability 1 ( p(s)=1 ) The probability that an event does not occur is. 1 minus the probability that the event does occur [ p(not happening)=1-p(happening) ] If two events have no outcomes in common, the probability that one or the other occurs is the sum of their individual probabilities.
