No. of Persons= 16

Step-by-step explanation:

There was a one phone line

Average no of people calling = 60 in one hour

% of all callers at most can get busy signal

Probability < 0.6

Probability for less than 1 person on hold = 0.2642

No of persons = 0.2642(60)

= 15.852 or 16

16 persons in hour the company is able to put on hold
