Section Starter Question
How do you evaluate cumulative binomial probabilities when the value ofn
is large, and the value ofpis small?
Key Concepts
- We can make a simple mathematical model of a financial derivative
using only the idea of a binomial probability. - We must investigate the sensitivity of the model to the parameter values
in order to completely understand the model. - This simple model provides our first illustration of the model cycle
applied to a situation in mathematical finance, but even so, it yields
valuable insights.
