5.5 The grade appeal process at a university requires that a jury be structured by selecting six individuals randomly from a pool of ten students and six faculty.
Possible combination of selecting 6 from total 16 members = 16C6 =8008
(a) What is the probability of selecting a jury of all students?
Possible combination of selecting 6 from total 10 STUDENTS = 10C6 =210
Possible combination of selecting 0 from total 6 FACULTY = 6C0=1
probability of selecting a jury of all students = (10C6)(6C0)/16C6
=(210*1)/8008 = 0.0262238
(b) What is the probability of selecting a jury of all faculty?
Possible combination of selecting 0 from total 10 STUDENTS = 10C0 =1
Possible combination of selecting 6 from total 6 FACULTY = 6C6=1
probability of selecting a jury of all students =(1*1)/8008 = 0.0001248
(c) What is the probability of selecting a jury of three
students and three faculty?
Possible combination of selecting 3 from total 10 STUDENTS = 10C3 =120
Possible combination of selecting 3 from total 6 FACULTY = 6C3=20
probability of selecting a jury of all students =(120*20)/8008 = 0.2997
