I can't find anything about the Binomial when it is multiplied by a constant. For instance, if the original distribution describes distances in miles, then multiplying all values by 1.609 describes the same distances in kilometers. One way to compute probabilities for a normal distribution is to use tables that give probabilities for the standard one, since it would be impossible to keep different tables for each .
