What's on a Grade 8 probability worksheet?

Each pack has up to 12 questions per page with a matching answer key, tuned to Grade 8, with beginner, intermediate, and advanced options so a teacher, tutor, or parent can match the learner's level.

How do you calculate probability?

Divide the number of favourable outcomes by the total number of possible outcomes, then simplify. It can be written as a fraction, a decimal, or a percent.

How do you find the probability of two independent events both happening?

Multiply their individual probabilities: P(A and B) = P(A) × P(B).

Can a probability be more than 1?

No, probability ranges from 0 (impossible) to 1 (certain).

How do you find P(A or B)?

If A and B can't both happen (mutually exclusive), add their probabilities. If they can overlap, add them and then subtract P(A and B) so the overlap isn't counted twice.

What is conditional probability?

The probability of an event given that another event has already happened, e.g. the probability a second card is red, given the first one drawn (and not replaced) was also red.

Why Grade 8 probability practice matters

What fraction of the outcomes actually go your way? That question, turned into a number between 0 and 1, is exactly what a 40 percent chance of rain means.

Grade 8 sits between Grade 7 and Grade 12 in Mathter's probability sequence, building on the earlier grade before Grade 12 extends it further.
