Using Algebra to Solve Probability Problems (with clues) WORKSHEET DESCRIPTION

This worksheet uses an ongoing theme of yellow and white counters in a bag to encourage pupils aiming for a grade 8 or grade 9 to think about how to combine their knowledge of algebraic manipulation and probability in order to solve problems. Within this worksheet, you will find four carefully designed exam-style questions, each needing to be set up and tackled in slightly different ways.

This version of the worksheet contains clues which can be particularly beneficial for classes or individuals who may require assistance when setting up their probability trees with algebraic expressions. See our version without clues if needed for you students.

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