Assume that each of the 6 possible outcomes is equally likely to occur on any 1 roll of the die. Calculate the probability that the number 2 comes up at most 27 times. Round your final answer to 3 significant digits. Use approximation to the binomial distribution and include the correction for continuity. Sketch the standard normal graph. \n" ); document.write( "
