Premium Probability Without Replacement | Maths Codebreaker | Answers Included

PREMIUM RESOURCE - available to purchase; this is not a free download.

Calculate two-event probabilities without replacement, including at least one outcomes.

This Premium paid resource contains one complete A4 pupil worksheet with 20 questions and a matching answer page with workings, plus a product-family guide. Pupils solve the maths, match answers to letters in the code grid and decode the hidden words.

Difficulty: Level 8 of 10 within this range (1 is easiest; 10 is most demanding). These levels are a guide to relative challenge, not GCSE grades.

Three questions from this worksheet:
1. A bag has 3 red and 2 blue counters. Find the probability of choosing two blue counters in two draws without replacement.
2. Remove one blue counter from 2 red and 8 blue counters. Find the probability that the next randomly chosen counter is red.
3. A bag has 6 red and 2 blue counters. Find the probability of choosing two red counters in two draws without replacement.

Use for focused practice, consolidation, homework or a lesson activity after teaching the method. Print the pupil page for learners and retain the answer page for checking. Follow the rounding and unit instructions on the sheet.

This resource belongs to a completed 100-topic Maths Codebreakers range. Halloween codebreaker resources are also available. A mixed-topic revision codebreaker range is coming soon. These other ranges are separate resources and are not included in this download.
