Conditional Probabilities: Learn It 3

  • Describe and find conditional probabilities.
  • Understand the concept of independent events.
We use a contingency table, sometimes called a two-way table, to organize data on two categorical variables at the same time. A contingency table provides a way of portraying data that can facilitate calculating probabilities. The table displays sample values in relation to two different variables that may be dependent or contingent on one another.
Conditional probability is defined as the likelihood of an event occurring based on the occurrence of a given event.
