For a new project, a landscape architect is choosing trees. Seven different tree species are available for the architect to select from: a Maple, a River Birch, an Oak, a Sycamore, a Chestnut, a Blue Spruce, and a Pine. There are two separate areas, named area 1 and area 2, in which the trees will be planted. The trees must be planted in accordance with the following constraints: <br>
<br>
‥ Each area contains three different types of trees, and there are only three types of trees in each area. <br>
‥ The same type of tree cannot be planted more than once in either area. <br>
‥ If an area contains a river birch, then the area cannot contain either a blue spruce or a pine. <br>
‥ If an area has a sycamore tree, it must also contain either a river birch or an oak. <br>
‥ Any area that contains an oak must also contain a maple. <br>
