The uniform distribution means that every outcome in the range from 20 to 60 minutes is equally likely. The range of possible delivery times is 60 - 20 = 40 minutes. If the delivery time is at least 25 minutes, we are looking at the range from 25 to 60 minutes, which is 60 - 25 = 35 minutes. The probability is the favorable range (35 minutes) over the total range (40 minutes), which is 35/40 = 0.875.
