I want to be sure I’ve got this right. There are six (presumably distinguishable) dice. I want to demonstrate that each is capable of showing all six faces.
Paul lets me roll all six (and tabulate which individual dice showed which numbers) charges $1 for the combined roll, and pays $50 when the tabulations show each die has shown all six faces.
Peter has me roll one die at a time, charges $1 for the individual roll, tabulates the results, and pays $20 when each die has shown all six faces.
my Termination condition is seeing all six numbers on the table at once. Paul has me roll all 6 dice each time, and only pays me if I roll a full straight (123456). Peter lets me roll one die at a time, once I’ve rolled all six dice, he lets me improve my hand by rolling a single die that duplicates another one, and pays once all six numbers are showing.
