Your lawn mower does not start on the first try 1/6 of the time. Design and use a simulation with number cubes to estimate the probability that your lawn mower will not start on the first try exactly one of the next two times you mow the lawn.

An application on your phone correctly identifies four out of every six songs. Design and use a simulation with number cubes to estimate the probability that at least three of the next four songs are correctly identified.
