Document Summary
Ggr 270 lecture 5 october 13, 2010. studying spatial patterns is a key concern of geographers: try to understand what has led to these patterns. geography is about describing, explaining, and predicting geographic patterns and processes. use probability for situations when patterns have some degree of uncertainty: ex: weather p. o. p. probability focuses on the occurrence of an event: where one of several outcomes could result, outcomes are (and must be) mutually exclusive. can be thought of as frequency of an event occurring relative to all other outcomes. p(a) = probability of outcome a occurring. max probability of an outcome is 1. 0: all probabilities must add up to 1. addition rule: used when finding probability of single independent events. p (a or b) = p(a) + p(b) www. notesolution. com. multiplication rule: used when finding probability of multiple independent events. p(a and b) = p(a) x p(b)
