Question 1202598
i think selection C is the answer
selection C says that b-m = m-a.
when the mean and the median and the mode are the same value, then you have a normal distribution.
a normal distribution is symmetric about the mean.
this means the area under the normal distribution curve is the same below the mean as above the mean.
here's one of many references from the web regaring normal distribution.
