Chapter 7 – Random Variables and Probability Distributions
... 7.6 Normal Distributions Normal Distributions (also called a normal curve) are important because: They provide a reasonable approximation to the distribution of many variables by using a function that matches all possible outcomes of a random phenomenon with their associated probabilities. Since t ...

... Find the probability mass function of X, b(x; 3, p): b(0; 3, p) = P (X = 0) = (1 − p)3 The underlying assumption is on the independence of the events: • A1 : getting an S in the first trial • A2 : getting an S in the second trial • A3 : getting an S in the third trial A1 , A2 , and A3 are mutually ...

... Also good to know is that the sum of two Poisson distributions with means 1 and 2 is a Poisson distribution with mean = 1 + 2. It gets a little trickier if two Poisson distributions or more are involved. A shortcut that can save you a significant amount of time is recognizing that the sum of two ...
