Write A if the statement is correct, B otherwise.  1. Latin letters denote a random variable while small letters denote a particular value of a random variable. 2. A random variable requires that every sample point be mapped to only one integer. 3. The values in the range of X are called mass points. 4. Each random variable may have more than one CDF. 5. For discrete cases, the CDF of X at the point x is the sum of the individual probabilities of mass points that are less than x.
