Binomial distribution: p = .44 , n=7 Find P(4) Using Formula (Recommend Using stattrek.com to check results) Usingp and q are the probabilities of success and failure respectively. p = .44 , q = .56 = 35 (Using nCr button on Calculator) = .2304 Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus P(x) is binompdf(n, p, x-value). P(4) = binompdf(7, .44, 4)= .2304 Feeling comfortable with Your calculator is key to Your success working with the various Distributions.
