What's on a Grade 7 probability worksheet?

Each pack has up to 12 questions per page with a matching answer key, tuned to Grade 7, with beginner, intermediate, and advanced options so you can match the child'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.

Grade 7 examples by level

BeginnerA bag has 1 red and 3 blue marbles. P(red) =1/4
IntermediateP(spinning blue or green on a 4-colour spinner AND rolling a number greater than 4 on a die) =1/6
AdvancedP(spinning red on a 4-colour spinner AND rolling a number greater than 4 on a die) =1/12

Real problems from the generator: always mathematically correct, and every pack is different.

Why Grade 7 probability practice matters

Probability underlies statistics, games, risk, and decision-making, a key numeracy skill for everyday life.

Grade 7 sits between Grade 6 and Grade 8 in Mathter's probability sequence, building on the earlier grade before Grade 8 extends it further.
