The probability is 
Step-by-step explanation:
From the question we are told that
The completion times for a job task range from 10.1 minutes to 19.2 minutes
Generally given that the completion times is uniformly distributed then the probability that it will require between 12.7 and 16.8 minutes is mathematically represented as


64 percent—64/100–0.64
12.5 percent—1/8—0.125
140 percent—1 and 40/100—1.4
275 percent—2 and 3/4–2.75
8 percent—8/100–0.08
