      the normal distribution, however, is that it supplies a positive probability density to every value in the range (1 ;+1), although the actual probability of an extreme event will be very low. In many cases, it is desired to use the normal distribution to describe the random variation of a quantity that, for physical reasons, must be strictly ...

      A continuous random variable is normally distributed or has a normal probability distribution if its relative frequency histogram has the shape of a normal curve. In Section 3.2, we introduced the Empirical Rule, which said that almost all (99.7%) of the data would be within
