If a randomly thrown dart hits the board below, what is the probability it will hit the shaded region?

The board is split into 8 pieces 7 pieces are shaded 1 is not shaded

The probability of hitting the shaded region would be 7 out of 8, because there are 7 shaded pieces out of the total 8 pieces on the board. So the probability would be 7/8 or approximately 0.875.
