While a robot vacuum was walking to Location B, it arrives at Location A with 3 roadsas shown below. The first road brings it back to Location A after 5 minutes of walk. The secondroad brings it back to location A after 10 minutes of walk. The last road leads to Location Bafter 6 minutes of walk. Assume that the robot vacuum is equally likely to choose among thethree roads at all times. Find the expected value of the time that the robot vacuum takes toLocation B from Location A.Road 2Road 1Location AStartRoad 3Location Bpoint

We are throwing darts at a disk (i.e. a filled in circle) shaped board of radius 5. We assume that the position of the dart is a uniformly chosen point in the disk. The board has a disk shaped bullseye with radius 1. Suppose that we throw a dart 1500 times at the board. Estimate the probability that we hit the bullseye at least 71 times.
