WebThe cumulative binomial probability table tells us that finding P ( X ≤ 3) = 0.6482 and P ( X ≤ 2) = 0.3980. Therefore: P ( X = 3) = P ( X ≤ 3) − P ( X ≤ 2) = 0.6482 − 0.3980 = 0.2502 That is, there is about a 25% chance that exactly 3 people in a random sample of 15 would have no health insurance.

WebA random variable X such that P (X = 1) = p and P (X = 0) = 1 p is said to be a Bernoulli random variable with parameter p. Note E X = p and E X 2 = p, so Var X = p p2 = p(1 p). We denote such a random variable by X Bern( p). Binomial distribution A random variable X has a binomial distribution with parameters n and p if P (X = k ) = n k p k(1 p)n.
