  • Mutually Exclusive Events
    Situations where two outcomes cannot occur together, represented by non-overlapping regions in a circle diagram.
  • Non-Mutually Exclusive Events
    Situations where two outcomes can occur together, shown by overlapping regions in a circle diagram.
  • Circle Diagram
    A visual tool using circles to illustrate relationships and overlaps between different events.
  • Overlap Region
    The area in a diagram where two events intersect, indicating both outcomes occur simultaneously.
  • Set Notation
    A symbolic way to represent events and their relationships, often using symbols like ∪ for 'or' and ∩ for 'and'.
  • Or Probability
    The likelihood that at least one of multiple events occurs, calculated using addition and sometimes subtraction.
  • Addition Rule
    A formula for finding the probability of either of two events, adjusting for any overlap between them.
  • Simplified Fraction
    A reduced form of a probability ratio, making interpretation and comparison easier.
  • Decimal Representation
    A way to express probability values as decimals, aiding in easier interpretation and comparison.
  • Individual Probability
    The chance of a single event occurring, used as a building block in combined probability calculations.
  • Overlap Subtraction
    The process of removing double-counted outcomes when calculating the probability of non-mutually exclusive events.
  • Set Union
    The combination of all outcomes from two events, represented by the ∪ symbol in set notation.
  • Set Intersection
    The collection of outcomes common to both events, represented by the ∩ symbol in set notation.
  • Total Possible Outcomes
    The complete set of all distinct results that can occur in a probability experiment.
  • Exclusive Region
    A part of a diagram representing outcomes unique to one event, with no overlap with others.
