A high Luck Index requires a low standard deviation. To get lucky, you need to roll the dice as many times as possible. A person who applies for 1 job has a binary outcome (lucky/unlucky). A person who applies for 1,000 jobs forces the Index of Luck by Chance to converge on their actual skill level.
The Index of Luck by Chance is only as good as its inputs. There are three common pitfalls where the index produces nonsense:
It looks like you’re asking for a guide to the phrase — though this isn’t a standard statistical or technical term. You may be referring to one of these concepts: index of luck by chance
Activities like the lottery or short-term stock trading, where randomness dictates the winner.
Humans are naturally wired to find patterns, even where none exist. This cognitive bias often inflates our perception of chance. The Law of Truly Large Numbers A high Luck Index requires a low standard deviation
Suppose the probability of finding a street parking spot immediately in your city is 10% (0.1). Over 30 days, by chance, you should find 3 immediate spots.

The formula is deceptively simple:
The concept of "luck by chance" also finds a home in the mechanics of digital worlds, where it is expressed through precise mathematical formulas that govern probability. In the action RPG Path of Exile 2 , the system is designed to mitigate the extremes of fortune. A "lucky" roll is defined as rolling a random number twice and taking the better result, while an "unlucky" roll takes the worse result.
This yields a straightforward yet powerful effect. For a binary roll, such as landing a critical strike, the chance of success under a lucky modifier is represented by the formula: . If a character has a 40% chance to crit, applying a lucky modifier increases that chance to a reliable 64%. This mechanic directly manipulates the player's "index of luck," converting a random outcome into a more predictable advantage. In this context, luck is not passive fortune but an active attribute that can be stacked, managed, and optimized, giving players tangible control over chance itself.
