Calculating Probabilities WORKSHEET

Suitable for Year groups: Year 7
GCSE Tier: Foundation
Targeting grades: 1-3
Prerequisite knowledge: Use the language of probability.
Learning Objective: Use appropriate language to evaluate the outcomes of simple events

Calculating Probabilities WORKSHEET DESCRIPTION

Here students are given nine different scenarios/events, such as ā€œYou will spin a 10 or less than 10 on a fair spinner with 10 sections numbered 1 - 10.ā€ alongside a six-interval scale with ā€œimpossibleā€ at one end and ā€œcertainā€ at the other.

Learners must place an arrow on the scale next to each event to show the chance of the event happening. Learners are also asked to write this probability as a fraction.

All probabilities can be shown on an interval marker on the scales, although some fractions, such as 4ā„8, will need to be simplified before doing so.

All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions

Students should already be comfortable using the language of probability before attempting these exercises. This foundation will help them understand terms like 'impossible' and 'certain' as they work through the nine scenarios. Having this vocabulary in place means they can focus on the core skill of evaluating how likely different outcomes are to occur.
