Suppose that for a call center “ALPHA” want to hire some more staff. A Resume of 351 applicant for a job is received. For this job, it approved 153 applicants initially, rejected 110 outright, and on hold 88 for the future consideration. In the past, this call center has approved 20% of the on hold initial applications of applicants. Let I, R, and H represent the events that an applicant who applies for a job is approved Initially, Rejected outright, and on Hold for a call center need.

Use the data to estimate P(I), P(R), and P(H)

Are events I and R mutually exclusive? Find P (I ∪ R). 

Suppose an applicant applies for a job. What is the probability that the applicant will be approved for initially job or be on hold and later got the job in a call center?
