If you have 3 points spread out randomly so that no 3 points are colinear, how many lines can you draw using 2 points? (Hint start at 1 dot and connect lines as you add each dot, you might notice a pattern)

Answers

  1. The total lines you can draw using 2 points is 3 lines

    Permutation and Combination

    Combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the elements of the subset can be listed in any order and it has to do with selection. In a permutation, the order of arrangement does not matter.
    From the given question, we are to randomly draw two points from the given 3 points. This is a combination question since it is selection. The combination formula is given as;
    nCr = n!/(n-r)!r!
    3C2 = 3!/(3-2)!2!
    3C2 = 6/2!
    3C2 = 3ways
    Hence the total lines you can draw using 2 points is 3 lines
