A target is made of a blue square inside of a red square. The blue square has an area of 64 square units, and the red square has an area of 196 square units.
Assuming it hits the target, what is the probability that a dart will land in the red region?
a. 0.25
b. 0.33
c. 0.67
d. 0.75
The probability that a dart will land in the red region is equal to the ratio of the area of the red square to the total area of the target.
The total area of the target is 196 + 64 = 260 square units.
The probability is therefore 196 / 260 = 0.75.
Therefore, the correct answer is d. 0.75.
