The tree diagram shows that there are a total of six sample spaces.  math------science  art     science---math     art---math  science     math---art     art---science  math    science---art    Based on the tree diagram, the probability that the science project is first is two over six. This is because science appears first in two out of the six sample spaces (boldened).
