• Course Objectives: Upon completion of the course, students should be able to:

• Solve simple probability problems with electrical and computer engineering applications using the basic axioms of probability.    (Chapters 1 – 5)
• Describe the fundamental properties of probability density and mass functions with applications to single and multivariate random variables.    (Chapter 3 – 6 and 8)
• Describe the functional characteristics of probability mass functions frequently encountered in electrical and computer engineering such as the Bernoulli, Binomial, Geometric, Poisson, and Uniform.    (Chapter 3)
• Describe the functional characteristics of probability density functions frequently encountered in electrical and computer engineering such as the Exponential, Gaussian, and Uniform.    (Chapter 4)
