With the same volatility for any asset price this is naturally the log-normal distribution of the asset price, as evident from the graph. Alternatively, the probability of ever getting in-the-money before maturity can be calculated in a very simple way in a binomial tree, using Brownian bridge probabilities.

Fire attacks come in five forms: burning people, burning provisions, burning tools, burning storage facilities, and burning arms. The use of fire should be rational and for a purpose.

When using fire attacks, the Art of War strategy is to follow-up swiftly to take advantage of the mayhem caused. Understanding when to set a fire means understanding the essential conditions for fire. Even if you would prefer to use fire in a different way, if the opportunity presents itself and conditions are right, take advantage. The use of arms should be considered carefully and only when all other tactics have been exhausted.
