Question

How many lines can be drawn from four distinct points if no three points are collinear?Give reason for your answer

Answer 1

Since two points determine a line and there are 4 points (and no 3 of them are collinear),
the number of lines that can be created is 4C2 = (4 x 3)/2! = 6.


there are 4 points , out of which 2 points are selected..

therefore 4C2
