Investigate a situation involving elements of chance 3 credits Internal
Key tips from Studyit:
- Be familiar with outcomes based on using dice, coins, and playing cards.
- Practise using simulations to solve probability problems.
- Record your data carefully.
- Check you have addressed every requirement that was asked for in planning your investigation.
- Use appropriate graphs to display your data. They should enable you to show features in relation to your investigation.
- Summarise your findings, referring to the steps you took to come to your conclusion.
- You may be expected to complete probability trees and use these.
- Multiply the probabilities along the branches of tree diagrams if you are asked for the probability that an event AND another event occur.
- Add the probabilities at the end of the branches if you are asked for the probability that an event OR another event occurs.
- Probabilities are best written as fractions, but may be written as a decimal or percentage. If written as a percentage, you must include the percentage sign.
- Probability must not be written as a ratio.
