10A.  A batch of parts contains 100 parts from a local supplier of tubing and 200 parts from a supplier of tubing in the next state. If four parts are selected randomly and without replacement, what is the probability that at most two parts in the sample are all from the local supplier?  (3 points)   10B.  In the 2004 presidential election, the results of the exit polls from Iowa is   Bush Kerry No college degree (62%) 50% 50% College degree (38%) 53% 46% If a randomly selected respondent voted for Bush, what is the probability that the person has a college degree?                                    (3 points)   10C. The probability that a bit transmitted through a digital transmission channel is received in error is 0.1. Transmissions are independent events. (a) What is the probability that the first four bits are transmitted correctly, and the fifth bit is in error? (b) Find the mean number of transmissions before the first error. (c) Find the standard deviation of the number of transmissions before the first error.     (4 points)
