Use two-way tables to calculate relative frequency or probability of events involving 'and' and 'or'

Reason For Learning

A two-way table is a useful tool to clarify the given information in a probability problem. This gives a graphical representation (a picture) of the problem and makes it a lot easier to understand the initial questions.

Learning Intention

You will be shown how to make a two-way table. A number of word problems will be presented to you. You will use two-tables to show each one as a picture. This will make the solving process a lot easier.
