Ideas of Chance & Uncertainty
MNU 322a
To run the tutorials simply click on the video you wish to play remembering to pause the video when attempting the questions! You should work through the exercises and homework in a squared jotter to keep all your work together. You should mark every section as soon as you finish it and write down your score.
For certain areas you will need a scientific calculator like the casio fx-85GT PLUS.
Once you have practiced the skills, be sure to see if you can apply them in the Applications questions at the bottom of the page. These questions should be revisited every so often as it is important to revise previous work so you don't forget it. Good luck! :)
Bronze Level
In this bronze tutorial we learn about the concepts of impossible, even chance and certain and how to place events with these outcomes on probability timelines. We also learn how to write probabilities as simple fractions.
VIDEO 129: Outcome 1 - Estimating probability. Grab a pen and your Rigour jotter. Make sure you try all the questions!
Video 130: Outcome 2 - Calculating simple probability. Remember to copy down the worked examples and take notes. These will help you revise and remember!
Video 131: Outcome 3 - Choosing at random. The final video in this module. After this, remember to think about your next steps!

OK you've learned the skills, but can you apply them??? Try the Applications section below and find out!
Applications
Now that you’ve practiced the skills, let’s see if you can apply them! In this section you will find application questions on probability. They may be set in a context, they could be a puzzle to solve or you may have to use a number of skills to solve the problems.
There are 8 questions in total here and you can answer them in ANY order at ANY time you like. Any questions that you don't get correct should be noted down and tried again at a later date - that's how we improve!
Can you answer them all correctly???
Question 1 - Try this one to kick us off. Remember to leave your answer as a fraction in its simplest form!
Question 2 - What are Anne's chances of winning this raffle? Should she have bought more tickets???
Question 3 - A tricky wee problem here involving 2 bags, lots of counters and comparing probabilities.
Question 4 - Try this probability question. Don't forget to simplify!
Question 5 - Read this question about the pupils of pupils very carefully!
