A probability mass function (pmf) is a function over the sample space of a discrete random variable X X which gives the probability that X X is equal to a certain value. Let X X be a discrete random variable on a sample space S S. Then the probability mass function f (x) f ( x) is defined as. f (x) = P[X = x]. f ( x) = P [ X = x].
Web• Consider two discrete r.v.s X and Y . They are described by their joint pmf pX,Y (x,y). We can also define their marginal pmfs pX(x) and pY (y). How are these related? • To find the marginal pmf of X, we use the law of total probability pX(x) = X y∈Y p(x,y) for x ∈ X Similarly to find the marginal pmf of Y , we sum over x ∈ X gender pay gap reporting regulations ukWebThus, the PMF is a probability measure that gives us probabilities of the possible values for a random variable.
