He examines these parts one at a time. a. Find the probability that the first part is suitable. (Round your answer to 2 decimal places.) Probability b. If the first part is suitable, find the probability that the second part is also suitable. (Round your answer to 4 decimal places.) Probability c. If the first part is suitable, find the probability that the second part is not suitable. (Round your answer to 4 decimal places.) Probability rev: 11_022015_QC_CS-31836

Explanation / Answer

a. Probability that the first part is suitable = 25/35 = 0.71.

b. If the first part is suitable, probability that the second part is also suitable = 25/35 * 24/34 = 0.5042.

c. If the first part is suitable, probability that the second part is not suitable = 25/35 * 10/34 = 0.2101.
