In 29-42, use the Binomial Theorem to find the indicated coefficient or term. The sixth term in the expansion of (3x + 2)8
Statistics 5-B Notes Random variable- a quantitative variable whose value depends on chance Discrete random variable- random variable where possibilities can be listed Standard Deviation of a discrete random variable = u x−¿ ¿ ¿2 P(X=x) ¿ ∑ ¿ ¿ Binomial Coefficients: n= n! nCr= (x X!(n−x)! Bernoulli Trials: 1.There are 2 and only 2 outcomes: (ex. Success if Fail, Odd or even) 2.Trials are independent- no trial affects another 3.The success probability remains the same through trails Binomial Probability Formula: p 1−¿ ¿ n x P (=x ) ()P ¿ x Steps to a binomial: 1.Identify a success 2.Determine P, the success probability 3.Determine n, the number of t
