Text: de Groot and Schervish, 3rd edition
Assignment: §3.1: 2,3,8,10; §3.2: 2,4,5,6; §3.3: 4,6,8,9
I omitted the sketches of graphs from these "text only" solutions. If anyone is
having difficulties with the graphs they are encouraged to ask me in class about it.
Problem 2 of §3.1
Those of you who shoot pool know that
1 + 2 + 3 + 4 + 5 = 15.
By the "sacred rule" we must have
5
x=1
cx = 15c = 1
and hence c = 1/15.
Problem 3 of §3.1
The following table shows the possible values of X:
1 2 3 4 5 6
1 0 1 2 3 4 5
2 1 0 1 2 3 4
3 2 1 0 1 2 3
