Applications of Probability Distributions
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
Sample: the first question, solved
Claims are normally distributed, μ=$5000, σ=$1200. Find P(claim exceeds $7000).
📘 Worked solution
✓z≈1.667. P≈0.0475.
And one from the hard end
Explain why we can use the normal distribution to approximate P(X≥60) for a binomial variable with n=200, p=0.25, rather than summing many binomial terms directly.
