For the expected value, you need to evaluate the integral ∫40yf(y)dy=∫y3(4 −y)64dy. In probability theory, the expected value of a random variable, intuitively, is the long-run .. This is because an expected value calculation must not depend on the order in which the possible outcomes are presented, whereas in a conditionally. Expected Value for a Discrete Random Variable. E(X)=\sum x_i p_i. x_i= value of the i th outcome p_i = probability of the i th outcome. According to this formula. Find an article Search Feel like "cheating" at Statistics?

If an event is represented by a function of a random variable g x then that function is substituted into the EV for a continuous random variable formula to get: Er ergibt sich zum Beispiel bei unbegrenzter Wiederholung des zugrunde liegenden Experiments als Durchschnitt der Ergebnisse. Since Marvin is a monkey, he will be guessing on each question. What is the EV of your gain? I also like that it shows the possibility of winning multiple prizes.
