The higher the volatility of the underlying asset, the higher the option premium. The formula for calculating the option premium is as follows: Option premium = Intrinsic value + Time value + Volatility value.
The formula for combinations, also known as binomial coefficients, is represented as nCr, where n is the total number of objects and r is the number of objects to be chosen. The formula for nCr is: nCr = n! / (r! (n-r)!)
