12-1  Organizing Data Using Matrices

Objective:  To organize data into a matrix. To add and subtract matrices and multiply a matrix by a scalar.

Essential Understandings: 
An electronic spreadsheet (i.e. Excel) is a type of matrix. You can use matrices to organize data. This may make it easier to perform calculations on the data.

12-7  Theoretical and Experimental Probability

Objective: To find theoretical and experimental probabilities

Essential Understandings: 
The probability of an event, or P(event) tells you how likely it is that the event is going to occur. You can find probabilities by reasoning mathematically or by using data collected by an experiment.
