5.67

In each of Exercises 5.67-5.72, we have provided the number of tri- als and success probability for Bernoulli trials. Let X denote the total number of successes. Determine the required probabilities by using a. the binomial probability formula, Formula 5. I on page 242. Round your probability answers to three decimal places. b. Table XI in Appendix A. Compare your answer here to that in part (a). 5.67 n = 4, p = 0.3, P(X = 2)
