ik=30.5 because 49 - 12 = 37.5 and 37.5/2+12=30.5
A.) Probability of selecting two students and two faculty members from 20 students and 5 faculty volunteers = no of ways of selecting two students and two faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C2 x 5C2) / 25C5 = 1900 / 53130 = 0.036 = 3.58%
b.) Probability of selecting three students and one faculty members from 20
students and 5 faculty volunteers = no of ways of selecting three students
and one faculty members from 20 students and 5 faculty volunteers
divided by the number of ways of selecting 4 people from 25 people = (20C3 x 5C1) / 25C5 = 5700 / 53130 = 0.107 = 10.7%
