The area of a checker board is 64 square units. 32 of the squares are red, and the other 32 are black.

If you used it as a dart bord, what is the probability that a dart will land in a black square?

The probability that a dart will land in a black square can be determined by dividing the number of black squares by the total number of squares on the checkerboard.

In this case, there are 32 black squares and a total of 64 squares on the checkerboard.

So, the probability of landing in a black square is 32/64 = 1/2.
