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?
A. 0.75
B. 0.50
C. 0.32
D. 0.25

Answer 1

B. 0.50

Since the board area is 64 and there are 64 equal squares, each square has area 1. The 32 black squares thus have total area 32, so the probability is 32/64 = 1/2 = 0.50.
