Six tools are in a bag - a hammer, wrench, drill, pliers, screwdriver, and measuring tape. You are trying to find the probability that you will pull out a different tool each time, if you replace the tool after each pull. Which simulation design would most accurately predict the result of choosing a tool three times?

You could roll a 6-sided die 3 times to simulate this. This is a good simulation because it has one side for each possible tool, and each roll is independent, just as selecting the tool with replacement would be.
