Apply probability concepts in solving problems
You need to apply probability concepts to solve real-world problems by calculating probabilities involving independent events, combined events, and conditional probabilities, as well as interpreting probability from tables, trees, and other diagrams. Your answers must include clear calculations and explanations written in the context of the problem.
You correctly calculate probabilities for independent and combined events, and interpret basic probability information from tables or trees, but explanations lack depth or fail to fully address the context of the problem.
You calculate probabilities accurately and interpret probability from various representations in context, with mostly clear explanations and working, but may have minor gaps in distinguishing between event types or in fully explaining your reasoning.
You calculate all probabilities correctly, clearly distinguish between mutually exclusive and independent events with proper justification using probability, interpret likelihood ratios with precision (including 'times as likely' vs 'times more likely'), and provide thorough contextual explanations with complete working that demonstrates strong probability understanding.
