Maslowich

Answer:

Step-by-step explanation:

In A, it says that 9s +7c can be lower or equal to 160. This is wrong.

In C, it says that 9s +7c can only be higher than 160, when the question says at least, which means it can also be equal to 160, making it wrong.

In D, it says that 9s +7c can be lower or equal to 20. This is wrong.

Through elimination, only B can be right.

Veseljchak [2.6K]

Answer: Probability that the entire batch will be accepted is 0.658.

Yes, this suggests entire batch of good CDs as it is the only condition to get accepted.

Step-by-step explanation:

Since we have given that

Number of CDs = 507

Number of defective = 65

Since the entire batch will be accepted.

So, the probability of success is p = $\dfrac{507-65}{507}=\dfrac{442}{507}=0.87$

and the probability of failure is q = $\dfrac{65}{507}=0.128$

Number of CDs selected = 3

So, Probability that the entire batch will be accepted is given by

$P(X=3)=^3C_3(0.87)^3\\\\P(X=3)=0.658$

Hence, Probability that the entire batch will be accepted is 0.658.

Yes, this suggests entire batch of good CDs as it is the only condition to get accepted.
