Quizplus · Accepted Answer

A dyadic relationship is a relationship between two individuals. Since we are considering 50 people, we need to calculate the number of possible pairs of these 50 people. This is given by the formula nC2, where n is the number of people and C2 represents the number of combinations of 2 people.

nC2 = 50C2
= (50 x 49) / (2 x 1)
= 1225

Therefore, there are 1225 possible dyadic relationships among 50 people. Hence the answer is option C.
