There are 12 points in a plane of which 5 points are collinear, then the number of lines obtained by joining these points in pairs is 12C2 – 5C2.

Question

State whether the statements in True or False.

There are 12 points in a plane of which 5 points are collinear, then the number of lines obtained by joining these points in pairs is ¹²C₂ – ⁵C₂.

Answer 1

FALSE

Required number of lines are ¹²C₂ – ⁵C₂ + 1

The number of lines obtained by joining these points in pairs is ¹²C₂ – ⁵C₂ + 1.
