Agroup of employees of unique services will be surveyed about a new pension plan. in-depth interviews with each employee selected in the sample will be conducted. the employees are classified as follows. classification event number of employees supervisors a 120 maintenance b 50 production c 1,460 management d 302 secretarial e 68 what is the probability that the first person selected is either in maintenance or in secretarial?

59/1000

Step-by-step explanation:

Given in the question, the section will follow

Event                    Number of employees                     Classification

A                                                      120                            Supervisors

B                                                       50                             Maintenance

C                                                       1460                           Production

D                                                       302                           Management

E                                                         68                              Secretarial

Total                                                  2000                               all employees

Probability that a person selected is in maintenance

P(M)= 50/2000 =1/40

Probability that a person selected in in secretarial

P(S)=68/2000 = 17/500

The probability that the first person selected is either in maintenance or in secretarial you add the two

1/40 + 17/500 = 59/1000

it has 4
