McClave & Sincich exercises:

3.3, 3.6, 3.22, 3.26, 3.28, 3.32, 3.36, 3.44, 3.51, 3.60, 3.62, 3.64, 3.70

*** Those taking STAT 515 for graduate credit should also do problem 3.132(a,b). ***

* Use your answer to 3.6(a) to help you with 3.26.

[NOTE: Hint for 3.44 clarified on 1/31/05:]
* For 3.44, first label the chips (W1, W2, R1, R2, B1, B2) and list ALL the outcomes in the 
sample space:  {(W1, W2), (W1, R1), (W1, R2), ...}.  Then count the outcomes that correspond
 to each specified event (dividing by the number of outcomes in the sample space to get each 
probability).

* For 3.64 and 3.70, first convert the specified percentages to probabilities.
