A simple dartboard has three areas…the main board has a radius of 8 inches, there is a circle with a radius of 6 inches, and the bullseye has a radius of 4 inches. What is the probability of a random dart landing inside the bullseye?

I would say:
probability = area of bullseye/area of main board

David,
Though strictly speaking the question ought to read "What is the probability of a random dart that hits the dartboard landing inside the bullseye?". A truly "random" dart could easily miss  and that would make the probability uncalculatable without extra information on how likely it is to hit the board.
