Anna's bus runs every 25 minutes. If she arrives
at her bus stop at a random time, what is the
probability that she will have to wait at least
10 minutes for the bus? Assume that a stop
takes very little time, and let    represent
the 25 minutes between buses. If Anna arrives at
any time between A and C, she has to wait at
least 10 minutes until B. P(waiting at least
10 min)                           , or
    The probability that Elena will have to wait
at least 10 minutes for the bus is     or 60.

If a dart hits the target at random, what it the
probability that it will land in the shaded
region?

The radius of the bulls-eye of the dartboard is
8 inches. The radius of each concentric circle is
8 inches more than the radius of the circle
inside it. If a dart lands at random on the
dartboard, what is the probability that the dart
will hit in area C?

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.
