4.2: Probability Distributions for Discrete Random Variables

WebIn probability theory, a probability density function ( PDF ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be ... WebApr 24, 2024 · The probability density function ϕ2 of the standard bivariate normal distribution is given by ϕ2(z, w) = 1 2πe − 1 2 (z2 + w2), (z, w) ∈ R2. The level curves of ϕ2 are circles centered at the origin. The mode of the distribution is (0, 0). ϕ2 is concave downward on {(z, w) ∈ R2: z2 + w2 < 1} Proof.
