Check what you remember
Read the wording for your board, then hide it and explain probabilistic modelling in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
Applying probability models to real-world phenomena requires simplifying assumptions, most notably that trials are independent and event probabilities remain constant.
