Explanation:

WaterLevel, CoffeeGrounfs, and CoffeeBeans represent current levels of water, coffee grounds, and coffee beans

NAT denotes set of natural numbers

WATER$\_$THRESHOLD, GROUNDS$\_$THRESHOLD, and BEANS$\_$THRESHOLD are predefined for the minimum required levels of water, coffee grounds, and coffee beans

$\backslash$theta BrewResult indicate the brewing operation results. Which can include information such as: temp, volume, or strength.

As a result, the brewing can occur if there's enough water, coffee grounds, and coffee beans available in the machine and passes minimum thresholds.
