Recap of #1
 Derivation of formula for error rate (see handout).
 Graph of function (density plot). Emphasize
two things:
 I am not showing them what I expect them to do.
I am using the computer as an electronic blackboard.
 The computer is calculating the value of z; suggest
they imagine a point "z far out" from the cursor (i.e.,
sketch a surface)
 Graph of function (3d)
 Relate to part (b).
 Solve equation (MathView; first a table, then a
solution. See printout)


Recap of #2
 Simulate the scenario:
 Put students in pairs. One is Michael, the other
is Warden.
 Give each pair of students 3 pieces of paper,
labeled "Michael", "John", and "Quincy".
Have them simulate the scenario – assuming Warden picks prisoner
BEFORE Michael asks.
 Have them simulate the scenario – assuming
Warden picks prisoner AFTER Michael asks.
 Analyze it using tree diagrams (emphasize importance
of BEING CLEAR ON THE PROCESS AND REFLECTING IT IN YOUR DIAGRAM)
