Question No. 1: 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. a) Use the data to estimate P(I), P(R), and P(H). b) Are events I and R mutually exclusive? Find P (I U R). c) 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?

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

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