Question

2n points at equal distances are marked off on a circle. These points are randomly grouped into n pairs and the points of each pair are connected by a chord. What is the probability that each of the n chords constructed do not intersect?

Answer 1

Answer:

Probability,Pr = n (A)/ n (U) {where n (A)= number of required outcome; n (U)= total number of outcome.

Step-by-step explanation:

Let n be the probability that each cords constructed intersect.

Hence, the probability that each of the n chords constructed do not intersect is n-1
