Chapter 1. Basic Probability Review

Page 29, Property 1.8.   This property should read V[X₁ + X₂] = V[X₁] + V[X₂] + 2 cov(X₁,X₂).

Page 42, Problem 1.25.   Second paragraph, second line, change the word “variances” to “standard deviations”.

Chapter 4. Poisson Processes

Page 118, Line 11.   Replace 0 with t in the equation Pr{T ≤ 0} = 1 - Pr{T > 0} = ...  ; thus it should read
Pr{T ≤ t} = 1 - Pr{T > t} = ...

Page 119, Second line of first equation.   Missing negative sign in exponents; should be -1.4, not 1.4.  Thus it should read
= 1 - ( e ^-1.4 + 1.4 e ^{- 1.4}  + ... span>

Chapter 11. Replacement Theory

Page 320, Problem 11.5.   This problem should refer back to Problem 11.4, not Exercise 8.4.
