Chapter 4 Probability Part 4 Youtube For any event a, the probability of a is between 0 and 1 inclusive: 0 ≤ p (a) ≤ 1. • the probability of an impossible event is 0. • the probability of a event that is certain to occur is 1. example: using a standard 6 sided die, find: • p (rolling a number greater than 7) = 0 • p (rolling a number less than 7) = 1. Complete parts (a) through (c) below. a. find the probability of randomly selecting a student who spent the money, given that the student was given four quarters = 0.738. b. find the probability of randomly selecting a student who kept the money, given that the student was given four quarters = 0.262.

Study with quizlet and memorize flashcards containing terms like 4.1 randomness, 4.2 probability models, random and more. Chapter 4 probability section 4 2: fundamentals section 4 3: addition rule sections 4 4, 4 5: multiplication rule section 4 7: counting (next time) the big picture of statistics 2 what is probability? probability is a mathematical description of randomness and uncertainty. possible outcomes:random experimentis an experiment.

The characteristics of a probability distribution function (pdf) for a discrete random variable are as follows: each probability is between zero and one, inclusive (inclusive means to include zero and one) the sum of the probabilities is one; 4.2 mean or expected value and standard deviation. Chapter 4: continuous random variables and probability distributions 4 example 3 accidents along a certain stretch of road are presumed to occur a dis tance of x miles from the nearest city center, where x ˘unif(100,150). compute 1. p (110 x 130) 2. p (127 < x 144) 3. p (x > 148).
