In the geometric model, the total sample space is represented as a large square. The prior probability P(H) determines the width of a vertical strip representing the hypothesis, and the likelihood P(E∣H) determines the height of the shaded region within that strip where the evidence occurs.
Conditions: Total sample space is normalized to unit area; Events H and E are treated as measurable subsets

For continuous variables like weather patterns or measurement tolerances, representing probabilities as grids of dots becomes cumbersome. Geometry offers a superior alternative by using areas (e.g., bar charts where width represents time/intensity and color indicates likelihood).
Conditions: Variables are continuous rather than discrete; Probabilities need to be visualized for intuitive understanding
