Mark Scheme (Results)
2025 PREDICTED PAPER
Pearson Edexcel GCE
Mathematics STATS Paper
9MA0/32
, m Mark Scheme - Question 1 (8 marks)
Why This Question Was Selected
This question was selected to:
• Introduce core probability principles early in the paper
• Test students on event relationships including mutual exclusivity and conditional
probability
• Provide a familiar real-world context {game outcomes) that avoids heavy
calculations
• Build early confidence before moving into statistical distributions or hypothesis
testing
It aligns with:
• Section 5.1 of the Edexcel A-Level Maths specification {Set theory, Venn diagrams,
probabilities of combined events)
• Common Paper 31 structure: start with an accessible topic, but push understanding
by the final part
Related Theory & Learning Points
• Mutually exclusive events have P(A n B) = 0
• P(A U B) = P(A) + P(B) - P(A n B)
• P(BIA) = P(AnB)
P(A)
