WebRisk-Neutral Probabilities 6 Examples of Risk-Neutral Pricing With the risk-neutral probabilities, the price of an asset is its expected payoff multiplied by the riskless zero price, i.e., discounted at the riskless rate: call option: Class Problem: Price the put option with payoffs K u =2.71 and K d =0 using the risk-neutral probabilities. €
WebP (A or B) = P (A)+P (B)-P (A and B). If A and B are independent (that is, the occurrence of a specific one of these two events does not influence the probability of the other event), then. P (A and B) = P (A)P (B). Without the assumption of independence, we have to modify this rule by replacing one of the individual probabilities by a ...
