Question

The growth of 100 young trees near a river is given below. (see picture)

If a tree grew more than 3 feet during the year, how much more likely is it that the tree was at most 50 yards from the river?

Answer 1

It is 91% more likely that the tree was atmost 500 yards from the river.

Explanation:

We are given with distance and height of 100 young trees near a river.

From that table, in total there are 55 trees which grow more than 3 ft during the year.

And among those 55 trees, 50 trees are atmost 50 yards from river.

Hence it is
`(50)/(55) =0.909`≈91% more likely that the tree was atmost 50 yards from the river.
