Answer:
0.5
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X higher than x is given by the following formula.

The mail arrival time to a department has a uniform distribution over 5 to 45 minutes.
This means that
.
What is the probability that the mail arrival time is more than 25 minutes on a given day?

So the probability that the mail arrival time is more than 25 minutes on a given day is 0.5.
The answer is A because 500 x 6 equals 3000 and 5000 minus 3000 equals 2000
