This concept
The 0-to-1 Probability ScaleConceptual concept
Check understanding
- Place events on a number line from 0 (impossible) to 1 (certain), expressing positions as fractions or decimals
- Explain that a probability of 0.5 means 'even chance' and connect this to the informal word 'likely'
- Convert between informal language ('very unlikely') and a numerical position on the 0-to-1 scale
“Can your child write the same probability as a fraction, a decimal, and a percentage — for example, knowing that an even chance is ½, 0.5, and 50%?”
