Apply probability distributions in solving problems
This standard asks you to solve real-world problems using probability distributions (like the normal distribution and binomial distribution). You'll apply your knowledge to calculate probabilities, interpret results in context, and explain what your calculations mean for the situation you're working with.
You calculate a probability correctly using the right distribution and show your working, but your interpretation of what it means is brief or not clearly connected to the real-world context.
You calculate the probability correctly, show clear working, and interpret your answer in context, but you may have minor gaps in explaining why this distribution was the right choice or how it applies to the specific situation.
You select and apply the correct distribution, show all working, and interpret your result by explaining exactly what it means for the real-world scenario—demonstrating that you understand both the maths and how it solves the actual problem.
