2.1.2 Chance outcomes

In the Really Big Ideas scenario each product development effort can have one of two outcomes: each project can either succeed or fail. Draw a small circle, or chance node, at the end of the branch for the smoke and fire detector. Draw a chance node at the end of the branch for the motion detector. From each chance node, draw two branches toward the right; one branch represents success and the other represents failure. Label the branches accordingly, as shown in figure 2.1.2.

Fig 2.1.2 Chance nodes, shown as small circles, lead to two or more possible outcomes. Draw each outcome as a branch from the chance node.
