Smartboard: From Impossible to Certain

From Impossible to Certain

Year 6 Mathematics · Probability · WA6MPSP1–P2

A probability scale from 0 impossible to 1 certain with everyday events placed along it. — Place and justify events on the 0–1 scale.

Where does it sit?

0 = impossible, 1/2 = even chance, 1 = certain. Justify placements with fractions.

More trials, less wobble

Observed results get closer to expected as the number of trials grows. Pool the class data to see it.
