In words define the random variables x and x
WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of successes (denoted ) occurs. For example, we can define rolling a 6 on a dice as a success, and … WebIn mathematics, a variable (from Latin variabilis, "changeable") is a symbol that represents a mathematical object.A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.. Algebraic computations with variables as if they were explicit numbers solve a range of problems in a single computation.

WebA random variable is a function from the sample space into the real numbers. A random variable that can take on at most a countable number of possible values is said to be discrete. Ex. Flip a coin four times. X = number of heads p(k) = P(X=k) = (4 k) (1/2)^k (1/2)^(4-k) p(0) = 1/16 p(1) = 4/16 p(2) = 6/16 p(3) = 4/16 p(4) = 1/16 Draw pmf
