A repair person is scheduled to be at your apartment between 9:00 am to 12:00 pm but you have to leave at 11:30 to help out a fr
iend. If the repair person is equally likely to be at your apartment any time during the appointment time, what is the probability that you will be there?
If we were to look as 1 hour as a 2 halves, and we have 3 hours, from 9 to 12, we can do 2 halves x 3 hours to equal 6, thus have a probablity out of 6. If you were to be there without leaving, there would be 6/6 times, meaning you wouldn't miss him, but since there is a half hour you are gone, the fraction then becomes 5/6 instead of 6/6. In this case, there is a 5/6 chance that you will be home the same time the repair person comes.
