Ant and Triangle Problem Interview Puzzle
Ant And Triangle Problem Interview Puzzle
Answer or Solution :
1. This "Ant and Triangle Problem" is a famous interview puzzle.
2. We need to find the probability that none of the ants collide.
3. Ants will not collide with each other only if they move either in counter-clockwise direction or in clockwise direction.
4. Every ant has two choices, that is they can pick either of the direction.
5. As there are 3 ants, and since they can choose any of the 2 directions each, the total number of possibilities is given as 2^3=8 possibilities.
6. Out of the 8 possibilities, only 2 will not cause collision.
7. Hence the probability of non-collision is 2/8 and the probability of collision is 6/8.
