There are six ways: $$(1,6), … In the event that the variables X and Y are jointly normally distributed random variables, then X + Y is still normally distributed (see Multivariate normal distribution) and the mean is the sum of the means. However, the variances are not additive due to the correlation. Indeed, $${\displaystyle \sigma _{X+Y}={\sqrt … See more In probability theory, calculation of the sum of normally distributed random variables is an instance of the arithmetic of random variables, which can be quite complex based on the probability distributions of the random variables … See more Let X and Y be independent random variables that are normally distributed (and therefore also jointly so), then their sum is also normally … See more • Propagation of uncertainty • Algebra of random variables • Stable distribution • Standard error (statistics) • Ratio distribution See more medicine hat tball
