Completing Two-Way Tables WORKSHEET
Suitable for Grades: 7th Grade, Geometry
CCSS: 7.SP.C.8, HSS.CP.B.6
CCSS Description: Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation. a. Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs. b. Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”), identify the outcomes in the sample space which compose the event. c. Design and use a simulation to generate frequencies for compound events. For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood?
Find the conditional probability of A given B as the fraction of B’s outcomes that also belong to A, and interpret the answer in terms of the model.

Completing Two-Way Tables WORKSHEET DESCRIPTION
Use this worksheet alongside Probability from Two-Way Tables. This worksheet provides the opportunity for learners to practice completing two-way tables from given information and then answer related questions. Section A has two partially completed tables that can be filled in using the data in the tables. Section B then provides information which can then be using to complete a given empty table that has the row and column heading provided. Section C also provides some information in words and phrases, but only this time the row and column headings are not provided.
