is answer \(\large 12\) ?
i can also do it by counting but i want to clear my concepts
that is the case for 3 points ,and total are their 4 points
i dont have any combonatrics concept here
the number of points are less so it is feasible to count
How many choices are there if you start from A ? |dw:1434217646278:dw|
i was thinking slecting two point from three
Exactly, 3C1 choices at starting vertex, after that how many choices are there at second vertex ?
3c1*2c1*2! cause u can like ADBA and ABDA
that will do
