Webb1 okt. 2024 · Probability can only be calculated when the event whose probability you’re calculating either happens or doesn’t happen. The event and its opposite both cannot occur at the same time. Rolling a 5 on a die, a certain horse winning a race, are examples of mutually exclusive events. WebbThe probability of all outcomes must add up to 1. The Expected Value (EV) shows the weighted average of a given choice; to calculate this multiply the probability of each given outcome by its expected value and add them together eg EV Launch new product = [0.4 x 30] + [0.6 x -8] = 12 - 4.8 = £7.2m.
