  1. event
    a subset of a sample space
  2. sample space
    all possible outcomes of a given experiment.
  3. simple event
    an event consisting of just one outcome. a simple event can be represented by a single branch of a tree diagram
  4. compound event
    a sequence of simple events.
  5. complement
    the complement of event e sometimes denoted e occurs when e dosent. the probabitity of e equals 1 minus the probabilityof e:p(e') =1-p(e)
  6. counting principle
    if an event a can occur in m ways and for each of these m ways n event b can occur in n ways then events a nd b can occur in m*n ways . this counting principle can be generalized to more than two events that happen in succession. so if for each of the m and n ways a and b can occur respectivley there is also an event c that can occur in s ways then abc can occur in mns ways
  7. tree diagram
    a tree shaped diagram that illustrats sequentially the possible outcomes of a given event
  8. outcomes
    the possible results of an experiment
  9. probability
    • the chance something will happen
    • probability = favorable outcomes
    • total outcomes
