The volume of a sphere can be calculated with this formula:
Where "r" is the radius.
You can observe in the figure that the value of the radius of this sphere is:
Then you can substitute this radius into the formula .

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.
