Lucky Sausages

Achievement Objectives:

Achievement Objective: S4-3: Investigate situations that involve elements of chance by comparing experimental distributions with expectations from models of the possible outcomes, acknowledging variation and independence.
AO elaboration and other teaching resources

Purpose: 

The purpose of this activity is for students to set up and run a simple probability simulation and to compare their experimental value of probability with the theoretical value.

Description of mathematics: 

The background knowledge and skills that need to be established before and/or during this activity are outlined in the diagram below:

This activity may be carried out with step by step guidance, or by allowing the student to follow their own method of solution. The approach should be chosen in sympathy with students' skills and depth of understanding.

Activity: 

 

A group of parents running a fundraising sausage sizzle are struggling to keep up with demand, so have got the BBQ turned up to the hottest setting.

As a result, one third of the sausages are burnt, a quarter are sold before they are cooked properly, but the rest are fine.

Use coloured counters to model this situation, to find the percentage probability, that the next customer is lucky enough to get a properly cooked sausage.

Comment on the results of your experiment.

 

The procedural approach  (show more)

  • The student is able to set up and run a simple probability simulation, with guidance and to compare the experimental value with the theoretical value of the probability.

The conceptual approach  (show more)

  • The student is able to set up and run a simple probability simulation, and to compare the experimental value with the theoretical value of the probability.
