Answer:
4/5
Explanation:
Information provided to us,
Total number of books = 30
Number of defective books = 6
Beginning with the solution of the answer,
Number of non-defective books = 30 - 6 = 24
Hence, probability of getting a non-defective can be calculated as follows,
Number of non-defective books / Total number of books
= 24 / 30
= 4 / 5
