Question
The number of straight lines that can be drawn out of 12 points of which 8 are collinear isChoices:- 39 49 59 29
Solution
The number of straight lines that can be drawn from n distinct points is given by the formula n(n-1)/2.
However, in this case, we have 8 points that are collinear (i.e., they lie on the same line), and 4 points that are not.
For the 8 collinear points, we can only draw one line, because any two points on this line will just form the same line.
For the remaining 4 points, we can draw 4(4-1)/2 = 6 lines.
So, the total number of lines we can draw is 1 (from the 8 collinear points) + 6 (from the 4 non-collinear points) = 7.
Therefore, none of the given choices are correct.
