Why do we have to define a distribution for a random variable? Choose the best statement below. Select one: O a. Observations from random variables vary from sample to sample. The distribution is the center and spread that help us understand the variable. O b. Observations from random variables vary from sample to sample. The distribution gives us the pattern and frequency in which we observe the variable. O c. The center and spread of the random variable are defined by the distribution. O d. Observations from a random variable must be understood. Knowing the distribution tells us what the next value vwill be.
