How do you solve probability math problems
WebJan 2, 2024 · Probability is determined by the number of outcomes you want compared to the total number of outcomes. For example, if you roll a 6-sided die, each outcome has a 1 out of 6 probability. Thanks! We're glad this was helpful. 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.
