A tree diagram is shown. The first three choices are art, science, and math. From art, one branch is math, science and the other branch is science, math. From science, one branch is art, math and the other branch is math, art. From math, one branch is art, science and the other branch is science, art.
Based on the tree diagram, what is the probability that the projects are in order of art, math, science? (5 points)

one over six

two over six

three over six

four over six

The probability is one over six.
