Using the combination formula, it is found that the probability that Lin and Kai are the 2 people chosen is of [tex]\frac{1}{66}[/tex].
The order in which the people are chosen is not important, hence the combination formula is used to solve this question.
What is the combination formula?
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem, 2 people are chosen from a set of 12, hence:
[tex]C_{12,2} = \frac{12!}{2!10!} = 66[/tex]
Lin and Kai corresponds to one combination, hence the probability that Lin and Kai are the 2 people chosen is of [tex]\frac{1}{66}[/tex].
