Calculating the Number of Negotiations

To calculate the number of negotiations that took place, we can use the formula for combinations, which is nC2 = n! / (2! * (n-2)!) where n is the total number of diplomats.

Given: - 4 diplomats conducted one-on-one negotiations with each other.

Calculation:

Using the formula nC2 = n! / (2! * (n-2)!) with n = 4: - 4C2 = 4! / (2! * (4-2)!) - 4C2 = (4 * 3 * 2 * 1) / (2 * 1 * 2) - 4C2 = 6

Answer: - There were 6 negotiations in total.
