Key Concepts: Basics of Probability & Binomial Distribution
Case Study: Dilemma of a Sales Executive
Abstracts: The case details a decision problem of a sales executive, Jaffer. He is an excellent employee in meeting his targets. He was given a chance to boost his professional career by giving a presentation to his fellow executives in Bangalore. As Jaffer would not like to miss the target, he would go to Bangalore, only if he is confident of completing the target. Therefore, Jaffer needs to compute the probability that no more than one day is lost in the remaining 29 days due to any of the reasons, and if this probability is sufficiently large, he may decide to accept the invitation. This case study introduces the method of structuring a problem in terms of identifying the decision problem(s), the alternatives, the uncertainties and choosing an alternative with the help of a well defined criterion. After introducing the basic concepts of Probability Theory, it is useful to demonstrate the use of Binomial distribution in resolving complex problems under uncertainty.
