15C3 - 5*3C3 - 3*5C3 = 420

Is this solution Helpfull? Yes (5) | No (2)  

kavana j  (8 years ago)

15C3 =455
them their are 3 rows and 5 column i.e:455-43=412

Is this solution Helpfull? Yes (5) | No (1)  

MAYUKHI CHANDRA  (9 years ago)

15C3 = 455

Is this solution Helpfull? Yes (4) | No (5)  

Pooja baghel  (9 years ago)

total no. of possible triangles=15c3
in row 5 points are in straight line and in column 3 points are in straight line.
so ans=15C3-3*5C3-5*3C3=420

Is this solution Helpfull? Yes (2) | No (1)  

Subhasree ghosh  (8 years ago)

15C3 - (3*5C3) -(5*3C3) - 6=414

Is this solution Helpfull? Yes (2) | No   

Raju Dahal  (9 years ago)

there are 15 points so the number of possible triangles are 15C3=455

Is this solution Helpfull? Yes | No (4)

394
455-(5+50+6)

Is this solution Helpfull? Yes | No

guys it should be 414 @sangita dutta you made correct approach but there was calculation mistake..:)

Is this solution Helpfull? Yes | No   

hariharan  (8 years ago)

I think the ans is 414
out of 455 chances we cannot make triangle in 36 ways so 455-36=419
3+3 chances in diagonal
10+10+10 in Straight line Like . . . . . any 3 points from this five cannot from triangle so 5c3 *3
1+1+1+1+1 for . there are 5 chances that cannot make triangle
so 414 chances we can make triangle
