Mean, median, and mode are:
A) equal to one another in any Poisson probability distribution
B) equal to one another in any normal probability distribution
C) different measures of center and, therefore, cannot possibly be equal to one another
D) different measures of center, but can equal each other only if the probability distribution is negatively or positively skewed
E) equal to one another in any normal probability distribution and different measures of center and, therefore, cannot possibly be equal to one another
