Summary: The probability of an event is the measure of the chance that the event will occur as a result of an experiment. The probability of an event A is the number of ways event A can occur divided by the total number of possible outcomes.
1 Place corned beef in large pot or Dutch oven and cover with water. Add the spice packet that came with the corned beef. Cover pot and bring to a boil, then reduce to a simmer. Simmer approximately 50 minutes per pound or until tender.  Add whole potatoes and carrots, and cook until the vegetables are almost tender.
Pour in the soy sauce, water, and brown sugar. Raise the heat to medium-high, and stir 4 minutes, until the sugar has dissolved and the sauce boils and slightly thickens. Remove sauce from the heat, and set aside. Place the sliced beef into a bowl, and stir the cornstarch into the beef, coating it thoroughly. Allow the beef and cornstarch to sit until most of the juices from the meat have been absorbed by the cornstarch, about 10 minutes. Heat the vegetable oil in a deep-sided skillet or wok to 375 degrees F (190 degrees C). Shake excess cornstarch from the beef slices, and drop them into the hot oil, a few at a time. Stir briefly, and fry until the edges become crisp and start to brown, about 2 minutes.
