Figure description

A horizontal decision tree with all nodes indicated by a small circle and most with labels. The nodes are connected, parent to child, by lines some of which have arrows. The unlabeled root node is to the left. From it proceed to the right the following children.

• first generation child labeled “Go to office” below this are
  • second generation child labeled “Go to faculty meeting” below this are
    • third generation child labeled “Vote for language requirement” (there is an arrow to this node)
    • third generation child labeled “Vote against language requirement”
  • second generation child labeled “Talk to student” (there is an arrow to this node) below this are
    • third generation child labeled “Encourage student to seek psychiatric aid”
    • third generation child labeled “Discourage student from seeking psychiatric aid” (there is an arrow to this node)
• first generation child labeled “Stay home” below this are
  • second generation child labeled “Do research for lectures” (there is an arrow to this node) below this are
    • third generation child labeled “Write lecture notes” (there is an arrow to this node)
    • third generation child labeled “Fix lunch”
  • second generation child labeled “Wash laundry” below this are
    • third generation child labeled “Put laundry in dryer”
    • third generation child labeled “Hang laundry on line” (there is an arrow to this node)

Below the main figure are \(t_1\) under the root node, \(t_2\) under the first generation, \(t_3\) under the second generation, and \(t_4\) under the third generation, Below this is a diagram of two nodes labeled A and B and connected by a line with an arrow (A to B). Following is the statement “= A would be followed by B”.
