Answer: N = 20C2 = 190
Therefore, Timika has 190 ways of choosing the pairs of children to lead the way
Step-by-step explanation:
Given;
Total number of children = 20
Number of children to lead the way = 2
Since all the children have equal possibilities of being selected to lead the way, and for the order is not important.
Then the number of ways to select two leaders from 20 children will be given by;
N = 20C2 = 20!/2!(20-2)! = 20!/2!18!
N = 20 × 19/2
N = 190
Therefore, Timika has 190 ways of choosing the pairs of children to lead the way
