On a product line that you manage, the number of inspections until the first failure each day is thought to have the geometric pmf.  For one 6-day week, you collect data: On Monday the first failure occurred on inspection #. On Tuesday the first failure occurred on inspection #. On Wednesday the first failure occurred on inspection #. On Thursday the first failure occurred on inspection #. On Friday the first failure occurred on inspection #. On Saturday the first failure occurred on inspection #.  This copywritten question is part of a quiz or exam given at Arizona State University.

An environmental testing station tests 98 parts in sequence.  The probability that a part passes the test is 0.77.  The parts are independent. This copywritten question is part of a quiz or exam at Arizona State University. It may not be posted or reproduced in any way without the permission of Dr. L. Chattin and Arizona State.  If you wanted to determine the probability that fewer than 85 of these parts pass, what is the best definition of the random variable you’d use? Select the answer that best completes the sentence.   “X is  _________________________________________. ”

A ferry in Long Beach, CA makes one trip each day to Catalina Island.  It is scheduled to arrive there at 10:00 am, but in actuality, it is always a little late. Its arrival time (in minutes after 10 am) has the exponential pdf with mean equal to 4 minutes. This copywritten question is part of a quiz or exam at Arizona State.  It may not be posted or reproduced without the permission of the author, Dr. L. Chattin, and Arizona State University. Determine the probability that the ferry arrives after 10:0 am on consecutive days (Monday through Friday).  Assume independence.
