The calculations for the expected value (mean) and variance of a discrete probability distribution are essentially identical to those for a :
A)frequency distribution
B)percent frequency distribution
C)relative frequency distribution
D)binomial probability distribution
E)continuous probability distribution

Question

Quizplus · Accepted Answer
