WebAug 30, 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. First, we will look up the value 0.4 in the z-table: Then, we will look up the value 1 in the z-table: Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859.

Given a known joint distribution of two discrete random variables, say, X and Y, the marginal distribution of either variable – X for example – is the probability distribution of X when the values of Y are not taken into consideration. This can be calculated by summing the joint probability distribution over all …
Web2 on independent and identical Bernoulli trials. For each trial, the outcome Y can take on values of 0 or 1, specified by probabilities P(Y=1) = π of success and P(Y=0) = 1- π of failure (where 0 ≤ π ≤ 1). A Bernoulli random variable has a mean of E(Y) = π. For n independent and identical Bernoulli trials, the number of successes follows a binomial …
