O RANDOM VARIABLES AND DISTRIBUTIONS Normal approximation to binomial V Suppose that a new treatment is successful in curing a common ailment 63% of the time. If the treatment is tried on a random sampl_e of 105 patients, approximate the probability that at most 64 will be cured. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)
