Instruction: Explain Bayes' theorem and provide the formula

Response: Bayes' theorem describes how to update probabilities based on new evidence. The formula is: P(A|B) = P(B|A) × P(A) / P(B). Where P(A|B) is the posterior probability, P(B|A) is the likelihood, P(A) is the prior probability, and P(B) is the marginal probability. This is fundamental in actuarial applications for updating risk assessments.

Instruction: Explain the binomial option pricing model

Response: The binomial model prices options by modeling stock price movements as a discrete binomial tree. At each node, price can move up by factor u or down by factor d. Key parameters: u = e^(σ√Δt), d = 1/u, risk-neutral probability p = (e^(rΔt) - d)/(u - d). The option value is calculated by backward induction: at maturity, value = max(S-K, 0) for calls, then work backward using V = e^(-rΔt)[pV_u + (1-p)V_d]. It can price American options (check for early exercise at each node) unlike Black-Scholes.
