If the single food server can process an average of 60 customers per hour. What is the probability an order can be processed in 2 minutes or less?
Expert Answer
Here mu = 60/60 = 1 per minute
Probability of taking t minutes or less in completing the task
Exp ( -mu x t)
= exp ( 1 x2) = 0.1353
The required probability is 13.53%.
