Illustrate about probability of collision?
Probability of collision:
There is a triangle and on this let’s assume that there are three ants one on each corner and are free to shift along sides of triangle what is probability what time they will collide?
Ants can go only along edges of triangle within either of direction, suppose that one is represented with 1 and other by 0, as there are 3 sides eight combinations are possible, while all ants are going in similar direction they won’t collide which is 111 or 000 therefore probability of collision is 2/8=1/4.
