RW: Hot Air Balloons
In a "Hare and Hounds" balloon
race, one balloon (the hare) leaves the ground first.
About 10 minutes later, the other balloons (the hounds) leave. The hare then lands and marks a square region as the target.
The hounds each try to drop a marker in the target.
a) Suppose that the houndsí markers are equally likely to land anywhere in a rectangular field that is 200 feet by 250 feet. The target is a 20X20 square that lies in the field. What is the probability that the marker lands in the target?
b) If the area of the target is doubled, how does the probability change?
c) If each side of the target area is doubled, how does the probability change

Negative and Positive Recency
The bullís eye of a standard dartboard has
a radius of about 1 inch. The
inner circle has a radius of 5 inches, and the outer circle has a radius
of 9 inches. Assume that when
a dart is thrown at the board, the dart is equally likely to hit any point
inside the outer circle.
a) What is the probability that a dart that hits the dartboard lands on the bullís eye?
b) What is the probability that a dart that hits the dartboard lands between the inner and outer rings?

Say that you hit the bullís eye 6 out of 20 times.
a) What is the probability that you hit the bullís eye with your first shot?
What is the probability that you hit the bullís eye with your 21st
arrow? What are the odds of
