12points are in plane 7points are in collinear how much line can be drawn please give me full solution

Answers

Answered by rakesh2222

For one line 2 points are required
so for 12 points
12C2 and out of these 7 are collinear
therefore 7C2 should be subtracted
so
12C2-7C2+1
1 is added because those 7 points make one line
The number of line is 12C2-7C2+1

rahulmishra5010: too many thanks to you

rakesh2222: your welcome
