This is a 15-page guide for teachers. This module continues the development of probability. In year 10, students consider situations involving two or three stages or two or three variables. In the special case of two- or three-step chance experiments, they assign probabilities to outcomes in situations involving selections either with or without replacement. In simple everyday situations, they explore and use the language of 'if', 'given', 'of' and 'knowing that'. Students use relative frequencies to estimate probabilities of the associated conditional statements.
