Find the probability that at least 722 of the surveyed adults use some type of vision correction. 73. Find the probability that between 750 and 778 of the surveyed adults use some type of vision correction. 74. Find the probability that at most 736 of the surveyed adults use some type of vision correction. 75. Find the probability that between 708 and 792 of the surveyed adults use some type of vision correction.
