Probability and two-way tables

Probability tells you how likely something is. On the Digital SAT Math section you often get a two-way table and have to find a probability from it.

This lesson starts with basic probability, then moves to two-way tables. You practice choosing the right number to divide by, especially for questions that say "given that." The animations highlight the cells in the table. Each part has a quiz, and the practice questions use tables like the ones on the test. Short examples with surveys and games make the ideas concrete, and every answer is explained in plain words.
