How many ways can you arrange eight items in pairs?

Answer 1

To arrange eight items in pairs, you first choose 2 items from the 8, then 2 from the remaining 6, and so on. The number of ways to arrange these pairs can be calculated using the formula for pairing, which is given by ( \frac{8!}{(2^4)(4!)} ). This accounts for the fact that the order of the pairs themselves does not matter. The final result gives you 105 ways to arrange the eight items into four pairs.
