Refer to the U.S. Army Corps of Engineers study of beach erosional hot spots, Exercise 2.5. The data on the nearshore bar condition for six beach hot spots are reproduced in the table. Suppose you randomly select two of these six beaches and count Y, the total number in the sample with a planar nearshore bar condition.
a. List all possible pairs of beach hot spots that can be selected from the six.
b. Assign probabilities to the outcomes in part a.

c. For each outcome in part a, determine the value of Y.
d. Form a probability distribution table for Y.
e. Find the probability that at least one hot spot in the sample has a planar nearshore bar condition.

Data from Exercise 2.5

According to the Union of Concerned Scientists (www.ucsusa.org), as of November 2012, there were 502 low Earth orbit (LEO) and 432 geosynchronous orbit (GEO) satellites in space. Each satellite is owned by an entity in either the government, military, commercial, or civil sector. A breakdown of the number of satellites in orbit for each sector is displayed in the accompanying table. Use this information to construct a pair of graphs that compare the ownership sectors of LEO and GEO satellites in orbit. What observations do you have about the data?
