What’s the probability that a CRV is in an interval? Take the di erence in CDF values (or use the PDF as described later). P(a X b) = P(X b) P(X a) = F X(b) F (a) For X˘N( ;˙2), this becomes P(a X b) = b ˙ a ˙ What is the Probability Density Function (PDF)? The PDF f is the derivative of the CDF F. F0(x) = f(x) A PDF is nonnegative and ...

Probability Distributions Cheat Sheet Story: A random variable X with a Bernoulli distribution with parameter p has two possible outcomes labeled by 0 and 1 in which X=1 (success) occurs with probability p and X=0 (failure) occurs with ... m>0, then X has a chi-square distribution with m degrees of freedom.

the distribution of the sample mean is: X¯= 1 n ∑ i=1 n Xi∼N(μ,σ 2 n) given that n is sufficiently large (n>30 ). If the population size N is finite, we add the finite population correction factor and the distribution of the sample mean is: X¯= 1 n ∑ i=1 n Xi∼N(μ, σ2(N−n) n(N−1)) .

Cheat Sheet for Probability Theory Ingmar Land 1 Scalar-valued Random Variables Consider two real-valued random variables (RV) X and Y with the individual probabil-ity distributions pX(x) and pY (y), and the joint distribution pX;Y (x;y). The probability distributions are probability mass functions (pmf) if the random variables take discrete
