Use the two-table to answer the questions. 3. Conditional probability can also be calculated using two-way tables. Conditional Probability: the probability of an event, given some other event has already occurred. These events fall within the individual rows and columns of the table. This probability can be calculated by finding the amount out of the total. P ( does not live with parents ) = amount total What is the amount? What is the total? Let us start with the total. In a two way table, always use the grand total (sum of all the cells) unless instructed otherwise.
