<t>So, I have [$]P(R \geq 0.03) = 1 - P(R \leq 0.03) = 1 - N(0.03)[$]where [$]N(x)[$] is the cumulative normal distribution function. I looked up in Hull "Options, etc." the approximation for [$]N(x)[$] in the "Cumulative Normal Distribution Function" section and it looks like I can just plug everyt...
