STAT 301 Lecture Notes - Sample Space, Collectively Exhaustive Events, Fair Coin
Document Summary
Probability is the likelihood of occurrence of some outcome or event. An experiment is a process that leads to only one outcome out of several possibilities. An outcome is a particular result of an experiment. An event is a collection of one or more outcomes. The sample space is all possible outcomes of an experiment. The complement of a, denoted ac, are all outcomes in which are not a. We say two events are mutually exclusive if both can"t occur at the same time. If i roll only 1 die, only one of a and b can occur, so a and b are disjoint. We say events are collectively exhaustive if at least one of the events must occur when the experiment is conducted. P(a) is the probability that event a occurs. Probability that both events a and b occur. Known as the intersection of a and b . Probability that a or b or both occur.
