At the Easter Show, there is a new game in which a small hoop pf radius 100mm is thrown onto a rectangular table 3 meters by 2 meters. If the hoop lands so that no part of it extends past the edge of the table, no prize is won. (In the diagram, hoops A, B and C would win prizes but hoops D and E would not)
