4. A survey of adults in a certain large town found that 85% of people wore a watch and 15% did not wear a watch. a) A random sample of 14 adults were taken. Find the probability (as a decimal rounded to four decimal places, if necessary) that more than 2 adults did not wear a watch. H b) A random sample of 200 adults were taken. Using a normal approximation for this binom distribution, find the probability (as a percent to two decimal places) that more than 175 wore a watch
