The probability that the entire batch will be accepted is 67.25%
Step-by-step explanation:

Then, in the same way, we calculate the probability if we take 5 CD's of the sample, taking into account that every time I take out one I will have one less in the total, and also one less that is Okay:
(67.25%)
