b. If G represents the event of having served in the Gulf War, and U represents the event of being under 45, find P(G given U) and P(U given G).
c. What was the most probable age group for a Vietnam War veteran in 2003?
d. If a veteran was 65 or over, what was the most probable war in which to have fought?
e. Suppose a similar table is constructed in 2008. How would the probability of a veteran having fought in World War II compare to the probability in 2003: would it have increased, decreased, or stayed the same?
