Probabilities of normal distribution
WebbX is a normally distributed random variable with mean ( μ) 84 and variance ( σ 2) 12, calculate: P ( X − 84 > 2.9) If X is normally distributed with mean ( μ) 400 and standard deviation ( σ) 8, find the value of k such that: P ( X − 400 < k) = 0.975 X is normally distributed random variable with mean m and standard deviation s . WebbThe normal distribution is a continuous distribution, so we can find the probability that x is greater than or less than a particular value, but not that x is equal to a particular value. Because the total area under the standardised curve is 1, Pr (z < β) is equivalent to the area to the left of β. Example 1

Webb23 apr. 2024 · A probability distribution function indicates the likelihood of an event or outcome. Statisticians use the following notation to describe probabilities: p (x) = the likelihood that random variable takes a specific value of x. The sum of all probabilities for all possible values must equal 1.
WebbIn probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment.
