問題文
A transport authority sorts its release toolkit into two families. One family limits who is able to look at a file; the other limits what the file itself carries. The authority also has to record what happens to the odds of a hit when it hands over only a slice of its rows instead of the entire book. Which pair fits the two families and that effect on the odds?
