You have been informed that the assessor will visit your home
sometime between 10:00 am and 12:00 pm. It is reasonable to assume
that his visitation time is uniformly distributed over the
specified two-hour interval. Suppose you have to run a quick errand
at 10:00 am.
a. If it takes 15 minutes to run the errand, what
is the probability that you will be back before the assessor
visits? (Round intermediate calculations to at least 4
decimal places and final answer to 3 decimal places.)
b. If it takes 30 minutes to run the errand,
what is the probability that you will be back before the assessor
visits? (Round intermediate calculations to at least 4
decimal places and final answer to 3 decimal
places.)
