Explanation / Answer
Strength of jury = 8 members
Students = 11
Faculty 12
a) Probability of selecting a jury of all students = 11C8/23C8 = 0.00034
b) Probability of selecting a jury of all faculty = 12C8/23C8 = 0.001
c) Probability of selecting a jury of five students and three faculty = 11C5 x 12C3 / 23C8 = 0.2073
