You see a game at a local fair. You have to throw a dart at a color wheel. Each section on the color wheel is equal in area. Let B = the event of landing on blue. Let R = the event of landing on red. Let G = the event of landing on green. Let Y = the event of landing on yellow. I f you land on red, you don’t get a prize. What is P(R)?

1. Bull's-Eye Bonanza. (Allotted Time 45 minutes) Suppose you want to throw a dart across a room at a wall-mounted target and hit the target exactly at its center point. We call this center point of the target its "bull's eye". The bull's-eye is a horizontal distance d from the dart's point of release and a height h above the dart's point of release. To hit the bul'seye, you have a choice of the speed s at which you throw...

Suppose you want to throw a dart across a room at a wall-mounted
target and hit the target exactly at its center point. We call this
center point of the target its “bull’s-eye”. The bull’s-eye is a
horizontal distance d from the dart’s point of release and a height
habove the dart’s point of release. To hit the bull’s-eye, you have
a choice of the speed v at which you throw the dart and a choice of
the angle θ...

differential equations proof please
Consider throwing a dart at the origin of the Cartesian plane. You are aiming at the origin, but random errors in your throw will produce varying results. We assume that: 1.) The errors do not depend on the orientation of the coordinate system. 2.) Errors in perpendicular directions are independent. This means that being too high doesn't alter the probability of being off to the right. 3.) Large errors are less likely than small errors. Let...
