A pentagon may be formed by joining 5 points lying on a plane. However, if we choose 3 or more points which are collinear, then the pentagon will not be formed.
Therefore, here we have 13 non-collinear points and 7 collinear points.
Number of pentagons that can be drawn= 13C5+ 13C47C1+ 13C37C2

A pentagon may be formed by joining 5 points lying on a plane. However, if we choose 3 or more points which are collinear, then the pentagon will not be formed.
Therefore, here we have 13 non-collinear points and 7 collinear points.
Number of pentagons that can be drawn= 13C5+ 13C47C1+ 13C37C2
= 1287 + 715 × 7 + 286 × 21 = 1287 + 5005 + 6006 = 12298
The correct answer is D.
how is it 13C47C1+ 13C37C2
pls can u explain why isit so?
OBSERVATION
ON ACTUAL MEASUREMENT, WE HAVE
AC = _________________, AD = ________________,AE = _______________,AF = ______________________,
AG = ___________________,
ROOT 2 = AC = ___________________________ ( APPROX )
ROOT 3 = AD = ________________________
ROOT 4 = AE = __________________
ROOT 5 = AF = __________________

How to simplify 4 - 2 root 3 by 2
hundredth root (1/4), 200th root (1/8), 300th root(1/32), 400th root (1/8)
1. 300th root (1/32)
2. 400th root (1/64)
3. 200th root (1/8)
4. 100th root (1/4)
