You sample the number of turkey oak seedlings in a
burned and unburned forest. You find 10 seedlings in
the burned forest and 90 in the unburned forest. If
the seedlings were randomly distributed in the two
forests, then the numbers of seedlings in each forest
would be the same. How many seedlings would you
expect in each forest if they were randomly
distributed?

Explanation:

1. Number of turkey oak seedlings in the burned forest (given): 10 seedlings

2. Number of turkey oak seedings in the unburned forest (given): 90 seedings

3. To find the total number of turkey seedings you must add the seedings found in the burned forest and the seedings found in the unburned forest:

4. If the seedlings were randomly distributed in the two forests, then the numbers of seedlings in each forest would be the same (given)

How many seedlings would you expect in each forest if they were randomly

distributed?

Since it is stated that the numbers of seeding in each forest would be the same, then you must divide the total number of seedings by 2:

Which means that you would expect 50 seedings in each forest if they were radomly distributed.
