Question

Help?

Answer 1

Maryanne chooses a random time between 2PM and 3PM to go check her mail. What is the probablity that maryanne's mail has been delivered when she goes to check on it?

Answer 2

Okay, so basically, since the question does not specify the times that the mail can me delivered, you should assume that the mail can be delivered any time of day. How many hours are in a day? 24. What time period does she check her mail? 2Pm - 3PM. How long of a time period is that? 1 hr. So the probability that her mail has been delivered when she goes to check on it is 1/24.

Answer 3

The answer is actually 1/4, but thanks anyways xD
