Question 4.5: Refer to Example 4.4. What is the probability that more than......

Let X represent the number of cars that have been recalled but not repaired. We wish to compute P(X > 1). Table A.1 presents probabilities of the form P(X ≤ x). We note that P(X > 1) = 1 − P(X ≤ 1). Consulting the table with n = 12, p = 0.2, and x = 1, we find that P(X ≤ 1) = 0.275. Therefore P(X > 1) = 1 − 0.275 = 0.725.
