Worked example
What it makes
Three questions from a easier quiz on probability, with the answers and worked solutions the quiz shows after checking.
1. A bag has 1 green, 6 black, 3 blue and 3 white counters. One counter is taken at random. What is the probability that it is black?
Options: 7/13 · 6/13 · 1/4 · 6/7
Answer: 6/13
There are 13 counters and 6 are black: P = 6/13.
2. A bag has 5 red, 8 black, 8 green and 7 blue counters. One counter is taken at random. What is the probability that it is blue?
Options: 1/2 · 1/3 · 1/4 · 3/4
Answer: 1/4
There are 28 counters and 7 are blue: P = 7/28 = 1/4.
3. A bag has 4 red, 1 yellow, 3 green and 8 white counters. One counter is taken at random. What is the probability that it is red?
Options: 1/3 · 1/4 · 1/2 · 3/4
Answer: 1/4
There are 16 counters and 4 are red: P = 4/16 = 1/4.
Who it's for
Who uses it
Maths teachers
Practice on probability as a fraction of equally likely outcomes.
Learners
See every outcome listed for dice and coins.
Tutors
Catch the 'every total from 2 to 12 is equally likely' mistake.
Good to know
What to consider
- Answers are fractions in simplest form.
- Level 1 uses bags of counters, level 2 adds 'not' questions, dice and cards, level 3 two dice and coins.
- Card questions assume a standard 52-card pack without jokers.
Questions
About the Probability Quiz Generator
Does it include tree diagrams?
Not as diagrams. Questions about two dice or several coins list every outcome instead.
How do I know the answers are right?
The questions are computed, not written by AI: each answer is worked out with exact arithmetic and checked again by a separate solver in our tests. Every question shows its worked solution after the learner checks their answers.
Can my students use it without an account?
Yes. Publish the Room and share the link: anyone with it can take the quiz, check their answers and read the worked solutions. You need a free account to keep and publish the Room.
