About this paper

CSC 211: Test 1, 26 November 2021 (1h30, max 30 marks), University of Buea, Faculty of Science, Dept of Computer Science: sample spaces/events for three experiments, a two-dice sum-divisible-by-4 problem, a hypergeometric chip-defect problem (full pmf/CDF/mean/variance), and a linear pdf on $[1,5]$ whose algebraically-solved coefficients make the density negative at $x=5$ -- flagged explicitly as an invalid source density rather than hidden.
