Your frontal lobe has been enhanced with the Probability Calculator, increasing your Luck by 1.— In-game description

The Probability Calculator Luck Implant is an implant perk in Fallout: New Vegas.

Requirements[]

The implant must be bought from Doctor Usanagi in the New Vegas medical clinic for 4,000 caps, or for 3,000 if one's Luck is below 4.

Effects[]

Gaining this perk grants a permanent +1 to Luck.

Notes[]

As with all of Usanagi's implants, if one has already purchased a number of other implants equivalent to the player character's Endurance attribute level, this implant cannot be purchased unless Endurance is raised one additional level, e.g. by taking one rank of Intense Training or gaining one of the four ending perks in the Fallout: New Vegas add-on Lonesome Road.

Behind the scenes[]

In the perk icon, Vault Boy is holding an Ace-high Straight Flush, better known as a 'Royal Flush', the highest-ranking hand in Poker. The odds of getting a Royal Flush in five-card stud-style poker is 0.000001539% or 649,740-to-1.
