Suppose that you choose 9 clocks at random. What is the probability exactly 2 of the clocks are defective. The probability that exactly 2 of the clocks are defective is 0.2597. Explanation: It is given that P(X=2)=9C2×0.152×(1−0.15)9−2 =9C2×0.152×(1−0.15)7 =0.2597 Number of trials =9 And 15% of the clocks p=0.15 and n=9 Answer Key In a large shipment of clocks, it has been discovered that 15 % of the clocks are defective. Suppose that you choose 9 clocks at random. What is the probability exactly 2 of the clocks are defective. Exam Page 2 Find each of the following probabilities: a. Find P(Z ≤ -0.87) . .80785. b. Find P(Z ≥ .93) . .00100. c. Find P(-.59 ≤ Z ≤ -.36). .27649. -12.0 points Answer Key Find each of the following probabilities: a. Find P(Z ≤ -0.87) . P(Z ≤ -0.87)= .19215. b. Find P(Z ≥ .93) . P(Z ≥ .93)=1- .82381= .17619. c. Find P(-.59 ≤ Z ≤ -.36). P(-.59 ≤ Z ≤ -.36)= .35942- .27760= .08182. [Show More]
