A soft-drink machine can be regulated so that it discharges an average of x ounces per cup. If the ounces of fill are normally distributed with standard deviation 0.3 ounce, give the setting for x so that 8-ounce cups will overflow only 1% of the time.

from the normal distribution table, the probability of X where X is greater than x is always greater than 0.5. how do i find a value x such that the probability of it overflowing is only 1%?
