The mail arrival time to a department has a uniform distribution over 5 to 45 minutes. What is the probability that the mail arr
VashaNatasha [74]

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.

P(X > x) = \frac{b - x}{b-a}

The mail arrival time to a department has a uniform distribution over 5 to 45 minutes.

This means that a = 5, b = 45.

What is the probability that the mail arrival time is more than 25 minutes on a given day?

P(X > 25) = \frac{45 - 25}{45 - 5} = 0.5

So the probability that the mail arrival time is more than 25 minutes on a given day is 0.5.
