Rev. F07 http://faculty.valenciacc.edu/ashaw/ 2 Rev.F08 4 What is a Random Phenomena? A random phenomenon is a situation in which we know what outcomes could happen, but we don’t know which particular outcome did or will happen. ht p:/ faculty. valenciacc . edu/ashaw/ Click link to download other modules. Rev.F08 5 What is a Sample Space? In general, each occasion upon which we observe a random phenomenon is called a trial . At each trial, we note the value of the random phenomenon, and call it an outcome . When we combine outcomes, the resulting combination is an event . The collection of all possible outcomes is called the sample space . ht p:/ faculty. valenciacc . edu/ashaw/ Click link to download other modules. Rev.F08 6 Sample Space and Event ht p:/ faculty. valenciacc . edu/ashaw/ Click link to download other modules. The probability of an event reports the likelihood of the event’s occurrence.

Rev.F08 8 Probability Notation ht p:/ faculty. valenciacc . edu/ashaw/ Click link to download other modules. Remember, each occasion upon which we observe a random phenomenon is called a trial . At each trial, we note the value of the random phenomenon, and call it an outcome . When we combine outcomes, the resulting combination is an event . The collection of all possible outcomes is called the sample space . If E is an event, then P ( E ) represents the probability that event E occurs . It is read “ the probability of E .” Rev.F08 9 Probability of an Event ht p:/ faculty. valenciacc . edu/ashaw/ Click link to download other modules. In this case, we can represent the probability of an event as P ( E ) = f / N .
