21. A game spinner is divided into 6 equally sized regions, as shown in the diagram. For Mark to win, the spinner must land on the number 6 . After spinning the spinner 10 times, and losing all 10 times, Mark complained that the spinner is unfair. At home, his dad ran 100 simulations of spinning the spinner 10 times, assuming the probability of winning each spin is $\frac{1}{6}$. Which explanation is appropriate for Mark and his dad to make? 1) The spinner was likely unfair, since the number 6 failed to occur in about $20\%$ of the simulations. 2) The spinner was likely unfair, since the spinner should have landed on the number 6 by the sixth spin. 3) The spinner was likely not unfair, since the number 6 failed to occur in about $20\%$ of the simulations. 4) The spinner was likely not unfair, since in the output the player wins once or twice in the majority of the simulations.
