This math topic focuses on calculating probabilities using permutations and their operation in various expressions. It provides practice in solving problems using `nPm` notation, which denotes the number of permutations of `n` items taken `m` at a time. The expressions involve operations like multiplication to simplify probability components. This subject helps students deepen their understanding of permutations and enhances their computational skills involving factorial-based computations in probability settings.
