**Geometric Probability**

Examples:

1. A desk is 29 inches wide and 60 inches long. On it, is a desk pad that is 17 inches wide and 22 inches long. If a person randomly flips a paperclip on the desk, what is the probability that it will land on the desk pad?

2. The cable guy will arrive at your home between 1:00 and 3:00 pm. What is the probability that you will miss the cable guy if you get home at 1:20 pm?

3. Assume that a dart you throw will land on the 1-ft square dartboard and is equally likely to land at any point on the board. Find the probability of hitting each of the blue, yellow, and red regions. The radii of the concentric circles are 1, 2, and 3 inches respectively.

If you change the blue circle as indicated, how does the probability of hitting the blue circle change? Explan. a) Double the radius.

b) Triple the radius.**Geometric Probability**
