likewhoa, take the two bunches as a single unit as u have to plant it in the middle. So there is 3 positions coming into picture in which only 1 is a way to plant the red bunches in the middle. So probability is = 1/3
Correct me If I am wrong

Consider each bunch as a single unit.
Total of ways to sort 4 bunches in a road = 4x3x2x1 = 24
Total of ways to sort the 2 white bunches in the middle = 2.
Total of ways to sort the other 2 red bunches on the sides = 2.
So the probability to sort 2 white bunches in the middle is (2+2)/24 = 1/6.
