Question

# 1) State the formula for the Binomial Probability Distribution, also state the domain. 2) Tell what the requirement for the Binomial experiment are. 3

Binomial probability
1. $$p(X=x) = C_x^n p^x (1 – p)^(n – x) Domain: x = 0, 1, 2, 3, … 2.$$1) a fixed number of trials 2) these are only two outcomes 3) Each trial is independent of the other 4) The probability of each outcome remains constant from trial to trial. 3. $$Mean = np\ Mean = \sum_{x=0}^\infty xp(x = x) 4.$$ SD = $$SD = \sqrt{np(1 – p)}$$
