CSC 211 Probability and Statistics Exam 2021

About this paper

CSC 211: First Semester Examination, 16 February 2021, Dr Dor C. \& Mme Tabo F.D. (the largest and most complex paper in the course: a 27-item MCQ section 'a' through 'aa', plus two further full-solution questions), University of Buea, Faculty of Science, Dept of Computer Science: most of the MCQ block answered 'none of these' since its option set is recycled from a differently-parametrized version of the same questions; a hypergeometric-like joint pmf for a 6-steel/4-copper-chip sample; and a severely invalid pdf $f(x)=ax+2$ on $[1,5]$ whose solved coefficient makes $E[X^2]$ negative (mathematically impossible), flagged very prominently with no fabricated standard deviation reported.
