Permutations and combinations are fundamental concepts in probability theory, playing a vital role in understanding and calculating the likelihood of events in various scenarios. In probability theory, we deal with uncertain events, and permutations and combinations allow us to analyze the possible outcomes and their probabilities. Permutations represent the number of ways in which a set of distinct objects can be arranged in a specific order. For example, if we have three different books (A, B, and C), the number of permutations would be the different ways we can arrange them on a shelf, such as ABC, BAC, CBA, etc. [1]

On the other hand, combinations deal with the number of ways to select a group of objects from a larger set without considering the order. For instance, if we want to select two books from the same three books mentioned earlier, the combinations would include AB, AC, and BC, as the order of the selected books doesn't matter [2].

Permutations in Probability Theory Permutations are used in probability theory to calculate the number of different arrangements of outcomes in an experiment. They help in finding the total number of possibilities or sample space [3]. Combinations in Probability Theory Combinations, on the other hand, are employed to calculate the number of ways to select specific outcomes from the total sample space, without considering the order. They are useful in determining the number of favorable outcomes [4] The Concept of Sample Space Sample space refers to the set of all possible outcomes of a random experiment. Understanding sample space is vital for calculating probabilities using permutations and combinations.
