Explanation / Answer

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
