Question

The area of a checkerboard is 64 square units. 32 of the squares are red, and the other 32 are black. If you used it as a dart board, what is the probability that a dart will land in a black square?

Answer 1

Each of the 64 equal squares has area 1, so the black squares total area is 32. Thus the probability is 32/64 = 1/2 (50%).
