The solutions manual generated on July 13, 2007 requires the following corrections:
• Ch 1, Problem 16, change $\bigcup\nolimits_i a_i$ to $\bigcup\nolimits_i \{a_i\}$. 6/20/08.
• Ch 1, Problem 17, change $\bigcup\nolimits_j c_{i j}$ to $\bigcup\nolimits_j\{ c_{i j} \}$. 1/18/09.
• Ch 1, Problem 51, 6th display, 2nd denominator: Change pn+1 to 1 − pn+1. 2/3/10.
• Ch 2, Problem 19, change both occurrences of $X_k=$10 to $X_k=$19. 10/7/10.
• Ch 5, Problem 50, the definition of h(t) is incorrect; it should be as in the text, h(t) = ln P(Y > t). 1/20/08.
• Ch 5, Problem 53, 3rd line, change "decode of" to "decode if". 11/30/10.
