Question At a carnival, contestants are asked to keep rolling a pair of dice until they roll snake eyes.  The number of rolls needed has a mean of 36 rolls, with a standard deviation of 5.4 rolls. The distribution of the number of rolls needed is not assumed to be symmetric. Between what two numbers of rolls does Chebyshev's Theorem guarantee that we will find at least 75% of the contestants? Round your answers to the nearest tenth. Enter the bounds in ascending order. Question Accord...
