Probability Theory
What is it
Undergraduate probability theory formalises probability using measure theory foundations, covering rigorous definitions of independence, conditional probability, and convergence of random variables.
Why it matters
This rigorous foundation is what allows probability to be applied with confidence to genuinely complex, high-stakes situations — from financial risk modelling to clinical trial design — where an informal, intuitive approach to probability would be dangerously unreliable.
Exam tip
When proving results about probability, be explicit about which axioms or previously proven theorems you're using at each step — probability proofs often look deceptively simple, and skipping the formal justification is where marks and rigor are lost.
