Grade 11 gradeMath subjectFree quiz

Grade 11 probability and statistics uses counting (permutations and combinations), independent and conditional events, expected value, and the normal model with z-scores. Students choose nPr when order matters and nCr when it does not. A z-score locates a value in standard deviations from the mean.

What you practice

These are the Grade 11 Probability & Statistics skills this quiz is built around.

Compute a permutation or combination and a classical probability from equally likely outcomes.
Use independence P(A and B) = P(A)P(B) or a conditional formula when needed.
Find a z-score (x − μ)/σ and interpret it as position in a roughly normal set of data.

A useful tip

Permutations count ordered lists; combinations count unordered groups. A committee of 3 from 10 is C(10,3), not P(10,3), unless seats are distinguished.
