WebSo if you roll a number cube six times, theoretically you would get each number 1-6 once. However, if you try an experiment (get a number cube, roll it and record what you get and do this six times) you may get each number once, but you are more likely going to have one or more number repeat. WebDetermining the sample events’ probability that is occurring is honestly: sum the possibilities together. For instance, if one has a 20% possibility of obtaining $20 and a 35% possibility of winning $30, the overall probability of obtaining something will be 20% + 35% = 55%.
