Ideas for July 2012 revamp of this problem
Spreadsheet
start with 4red 3black in prob and interactivity.
surprised?
why do we all end up with the same? with less than we started?
what would happen with five red and 3 black?
Given n black cards how many red cards do I need to turn a profit?
questions to consider
if I have equal numbers of red and black what happens?
twice as many red as black?
can I ever exactly break even?
What if I bet amounts other than 0.5?
what if I could have two more reds than blacks
