Geometric Probability Quiz

What is geometric probability primarily concerned with?

• Probability of shapes and colors

• Probability of numbers and letters

• Probability of areas and lengths

• Probability of time and speed

If a point is chosen randomly on segment AB, which contains segment CD, how do you calculate the probability that the point is on CD?

• Length of CD multiplied by length of AB

• Length of AB minus length of CD

• Length of CD divided by length of AB

• Length of AB divided by length of CD
