Stat 515 - Spring 2001 - Correctons to the Text

Page 123. The conditional probabilities in the middle of the page should be: P(B|A)=.05/.25=.20 and P(BC|A)=.20/.25=.80. The paragraph that follows is then correct .80 is to .20 as .2 is to .05, both are 4 to 1.

Page 169. In example 4.9 there is an error for p(0) and p(4). p(0)=1(1)(.9)4 and p(4)=1(.1)4(1) because .10 and .90 should both be equal to 1. The rest of those lines are correct.

Please e-mail me with any other suspected errors.
