Probability Trees

In this unit we introduce the idea of probability trees. This device is then used to calculate the theoretical probability of a number of events in a variety of situations

Level Five > Statistics

Achievement Objectives:

Achievement Objective: Calculate probabilities, using fractions, percentages, and ratios.

Resource

Many games of chance and activities in maths text books involve rolling two dice and combining the scores, usually by addition.Students often find the probabilities of such events difficult to calculate as they are confused between events (eg a score of 4) and outcomes (eg 3 and 1, 2 and 2, 1 and 3).This unit makes use of a variety of activities where the number of outcomes in the sample space is clearly different from the number of events.

Achievement Objectives:

Achievement Objective: Compare and describe the variation between theoretical and experimental distributions in situations that involve elements of chance.

Achievement Objective: Calculate probabilities, using fractions, percentages, and ratios.

Probability Distributions

This unit aims to introduce students to concepts that are important in probability.The emphasis should be on working slowly taking the time to let the students grasp the ideas that underlie the activities presented. All the ideas are important as a base for future learning in this area of mathematics.
