In probability theory, combinations and permutations are distinct concepts. 1. Combinations: The order of outcomes does not matter. 2. Permutations: The order of outcomes does matter. Let’s use three letters to illustrate both concepts: C, J, M. Suppose we’re using these letters to signify people on a team, … See more When the outcomes in a combination can repeat, you have repetition. With our pizza example, if you can choose a topping multiple times, such … See more When the outcomes cannot repeat, you are working with combinations without repetition. These calculations use the following equation for … See more In the previous examples, we calculated the number of combinations for different scenarios. However, we didn’t use them to calculate probabilities. In this context, a probability is the number of combinations considered to be an … See more
