What is the probability that the given fair spinner lands on a blue section?

What is the probability that the given fair spinner lands on a yellow section?

A real number is randomly chosen between 10 and 100. Find the probability that is closer to 50 than to 100.

A target board consists of three concentric circles of radii 6 cm, 12 cm, and 24 cm, which define three regions gold, red, and blue as shown in the diagram. If a dart is thrown randomly such that it hits the target, what is the probability that it will hit the red region?
