Suppose that in Sherwood Forest, the average radius of a tree is R= 1 m and the average number of trees per unit area is 0.005m^(?2). If Robin Hood shoots an arrow in a randomdirection, how far, on average, will it travel before itstrikes a tree?
teacher's hint: for any distance, how many trees on average will the arrow have hit?
then for what distance, the number of the tree=1?
