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)

Respuesta :

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

What are collinear points?

Collinear points are points that lines on the same line compared to coplanar points that lies on the same plane.

What is Permutation and Combination?

Combination and permutation are two different ways of grouping elements of a set into subsets. Combination has to do with selection while permutation has to do with arrangement.

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 = 3*2/2*1
3C2 3/1
3C2 = 3ways

Hence the total lines you can draw using 2 points is 3 lines
