Determine and compare the theoretical and experimental probabilities of an event happening
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
What is the theoretical probability of rolling a 4 on a standard 6-sided die?
📘 Worked solution
✓There is 1 favorable outcome (rolling a 4) out of 6 possible outcomes, so the probability is 1/6.
And one from the hard end
Design an experiment comparing theoretical and experimental probabilities for a 4-section spinner (theoretical probability per section = 1/4). Predict the expected count after 40 spins, then explain what would suggest the spinner is fair versus biased.
