such crew members, which he may assign to any ship.
is playing a game. In this game, players send out ships to complete voyages for profit. Each voyage has numerical requirements in at least one of the Coding, Anti-seasickness, and Pathfinding attributes (its programmer crew must remain both mentally healthy by programming, and physically healthy by eating decent food, all while not getting lost). The closer a player's ship comes to fulfilling these requirements, the greater its chance of success. A ship can hold five crew members, and each member contributes some constant to their ship's attributes. hasA voyage's chance of success is defined as the minimum ratio between a voyage attribute and the sum of all crew members in that attribute, and maxes out at . For example, if both the Anti-seasickness and Pathfinding requirements are met while the requirement for Coding is but the crew only provides , the voyage's chance of success will be .
Since
