Suppose you have two random variables, X and Y and their joint probability distribution function is f(x, y) over some appropriate domain.
Then the marginal probability distribution of X, is the integral or sum of f(x, y) calculated over all possible values of Y.
The joint probability of two discrete variables, X and Y isP(x, y) = Prob(X = x and Y = y) and it is defined for each ordered pair (x,y) in the event space.The conditional probability of X, given that Y is y is Prob[(X, Y) = (x, y)]/Prob(Y = y) or equivalently,Prob(X = x and Y = y)/Prob(Y = y)The marginal probability of X is simply the probability of X. It can be derived from the joint distribution by summing over all possible values of Y.
Marginal revenue is the change in total revenue over the change in output or productivity.
The probability is 0.The probability is 0.The probability is 0.The probability is 0.
The probability is 1.The probability is 1.The probability is 1.The probability is 1.

The marginal probability distribution function.
good question.
If f(x, y) is the joint probability distribution function of two random variables, X and Y, then the sum (or integral) of f(x, y) over all possible values of y is the marginal probability function of x. The definition can be extended analogously to joint and marginal distribution functions of more than 2 variables.
Marginal effects represent the change in the predicted probability of an outcome occurring as a result of a one-unit change in an independent variable, holding all other variables constant. In simpler terms, they quantify the impact of a specific predictor on the dependent variable. For example, in a logistic regression, a marginal effect of 0.05 for a variable means that increasing that variable by one unit increases the probability of the outcome by 5%. This interpretation helps in understanding the practical significance of each predictor in the model.

Marginal net benefits= Marginal benefit- Marginal cost
A marginal rating on a security assessment indicates that the security controls in place are insufficient to adequately protect the organization from potential threats and vulnerabilities. It suggests that while some measures are in place, they are not effectively mitigating risks, leading to a higher probability of security incidents. Organizations receiving a marginal rating should prioritize improvements to their security posture to address identified weaknesses.
Marginal cost is
The optimal level of output is where marginal costs = marginal damages.
In economics, marginal profit is the difference between the marginal revenue and the marginal cost of producing an additional unit of output.
Three stages of production are increasing marginal returns, diminishing marginal returns, and negative marginal returns.
In regards to marginal vs. non-marginal syndesmophytes. Marginal syndesmophytes (intervertebral bony bony bridges) are more commonly seen in ankylosing spondylitis. Where as non-marginal syndesmophytes are more commonly in reactive arthritis and DISH. Marginal syndesmophytes are delicate + symmetric; while non-marginal syndesmophytes are bulky + discontinuous.
