Answer:

Step-by-step explanation:
Given
-- total
--- defective
--- selected
Required
The probability of rejecting the batch
This means that at least one of the selected piece is defected.
So, we first calculate the probability that all the selected piece are accepted.
So, we have:

The denominator decreases by 1 because it is a probability without replacement; 180 is subtracted from the numerator to represent the number of non-defective CDs
So, we have:


Using the complement rule, the probability that the batch will be rejected is:


14:21 one is the right answer
Answer:
Step-by-step explanation:
Both terms have the same denominator, 7. So combining them is relatively easy. Rewrite 2 4/7 as 18/7 and then subtract 18/7 from 1/7:
1/7 - 18/7 = -17/7
Choose Answer 4: None of these are correct.
