WebE ( f ( X)) = ∫ D f ( x) p ( x) d x where D denotes the support of the random variable. For discrete random variables, the corresponding expectation is E ( f ( X)) = ∑ x ∈ D f ( x) P ( X = x) These identities follow from the definition of expected value. In your example f ( X) = exp ( − X), so you would just plug that into the definition above. WebOf course, a binomial variable X is not distributed exactly normal because X is not continuous, e.g. you cannot get 3.7 heads when tossing 4 coins. In the binomial, P(X ≤ a) + P(X ≥ a + 1) = 1 whenever a is an integer. WebA normal distribution, sometimes called the bell curve (or De Moivre distribution [1]), is a distribution that occurs naturally in many situations. For example, the bell curve is seen in tests like the SAT and GRE. The bulk of students will score the average (C), while smaller numbers of students will score a B or D. rickmarcumauthor.com
