A goes to the first teller‚ B to the second teller‚ and C queues. To standardize the answers‚ let us assume that TA is the length of time in minutes starting from noon until Customer A departs‚ and similarly define TB and TC . (a) What is the probability that Customer A will still be in service at time 12:05? (b) What is the expected length of time that A is in the system? (c) What is the expected length of time that A is in the system if A is still in the system at 12:05? (d) How likely is

questions. a. Use the multiplication rule to find the probability that the first two guesses are wrong and the third and fourth guesses are correct. That is‚ find P(WWCC)‚ where C denotes a correct answer and W denotes a wrong answer. b. Make a complete list of the different possible arrangements of 2 wrong answers and 2 correct answers‚ then find the probability for each entry in the list. c. Based on the preceding results‚ what is the probability of getting exactly 2 correct answers when 4 guesses

accessible as possible. The notes should be readable by someone who has taken a course in introductory (non-measuretheoretic) probability. The first part is about Markov chains and some applications. The second one is specifically for simple random walks. Of course‚ one can argue that random walk calculations should be done before the student is exposed to the Markov chain theory. I have tried both and prefer the current ordering. At the end‚ I have a little mathematical appendix. There notes are

Exemplar Theory Exemplar Theory refers to an approach of categorization in psychology using which individuals can make decisions by comparing new examples with the examples which is already present in their mind. Instead of relying on a single prototype‚ categories have many or known exemplars that fit into them. When you come across something new‚ you can compare it with all members of a category. The greater the number of exemplars the new item will match‚ the better will it adapt against all

(a) Use the Excel function NORM.S.DIST to calculate the following probabilities to four decimal places‚ where the random variable Z follows a standard normal distribution. Write your answers to four decimal places on this sheet and remember to draw the curves? For every second question‚ please use your tables to find the probability as well as Excel.
