Chapter 9.1, Problem 2ED

Refer to Example 4. States $D$ and $G$ are referred to as absorbing states because a student who enters either one of these states never leaves it. Absorbing states are discussed in detail in Section 9.3.

(A) How can absorbing states be recognized from a transition diagram? Draw a transition diagram with two states, one that is absorbing and one that is not, to illustrate.

(B) How can absorbing states be recognized from a transition matrix? Write the transition matrix for the diagram you drew in part (A) to illustrate.
