Now try to solve this on your own…

Solution :-

This problem can be easily solved by using probability. Each ant can move in two different directions, either clockwise or anticlockwise and we have total 3 ants, so a total number of ways these 3 ants can move simultaneously are 2 * 2 * 2 = 8. Now to avoid a collision all 3 ants should move in the same direction, either clockwise or anticlockwise. So a total number of ways these 3 ants can move simultaneously to avoid a collision are 2.

So probability will be 2/8 = 0.25
