Stochastic Processes
What is it
A stochastic process is a system that evolves over time with an element of randomness, generalising ideas from probability and Markov chains to model sequences of random events unfolding over time.
Why it matters
Stochastic processes are the mathematical language used to model unpredictable real-world systems that evolve over time — stock prices, particle movement, queueing systems — making this topic a genuine bridge to advanced applied mathematics.
Exam tip
Clearly define the state space and the time steps of the process before attempting any calculation — a vague or incomplete definition of the process is where most confusion in stochastic process problems begins.
