MATH8-Quarter4

• Probability


  Branch of mathematics that deals with uncertainty and the measure or estimation of how likely an event will occur
• Probability


  • Deals with decimals and fractions
• Experiment


  Activity in which the results cannot be predicted with certainty
• Outcomes


  Result of an experiment
• Sample space


  Set of all possible outcomes of an experiment
• Sample point


  Individual outcome in sample space
• Event


  Particular collections of outcomes
• Simple event


  Event with only one possible outcome
• Table


  Shows the first row and first column in each event
• Tree diagram


  Device consisting of line segments emanating from a starting point and from the outcome point
• Tree diagram


  Used to determine all possible outcomes of a probability experiment
• Systematic listing


  Organized or systematic way of listing the outcomes of an event
• Fundamental counting principle


  If one event can occur in m ways and a second event in n ways, and a third thing can occur in p ways, then the sequence of things can occur in m x n x p... ways
• A probability is a number between 0 and 1, inclusive
• The probability of an event that cannot happen is 0
• The probability of an event that must happen is 1
• Probability of a simple event

  Number of favorable outcomes / number of possible outcomes
