Question 200787
27): The computer systems department has eight faculties, six of whom are tenured. Dr Vonder, the chairman, wants to establish a committee of three department faculty members to review the curriculum. If she selects the committee at random: 
a) What is the probability all members of the committe are tenured 
[6C3]/[8C3]= 20/56 = 0.3571
=====================================

b) What is the probability that at least one member is not tenured? (Use the compliment rule)
P(at least one not tenured) = 1 - P(none not tenured)
= 1 - P(all tenured)
= 1 - 0.3571
= 0.6429
