Sunny_sXe [5.5K]
Let A represents the event that DVD has a video effect. 
So, 
P(A) = 1.5 %

Let B represents the event that DVD has a audio defect.
So,
P(B) = 0.8 %

A ∩ B represents that DVD has both audio and video defect.
So,
P(A∩B) = 0.4%

Part a)
A ∪ B represents that DVD has a video or audio defect. 

P(A∪B) = P(A)+P(B)-P(A∩B) = 1.5 + 0.8 - 0.4 = 1.9%

Thus the probability that the DVD purchased by the customer has a video or audio defect is 1.9%.

Part b) 
The complement of P(A∩B) will represent the probability that the DVD does not have video or audio defect.

So, the probability that DVD purchased by customer does not have video or audio defect is 1 - 0.4 = 0.96%

Answer:

Q = -6

Step-by-step explanation:

To find the answer to this, you first must multiply the first function by 2:

2 x (x - 3y = 4)

2x - 6y = 8

Which then means that the second function is the same. This means that to find Q you need to find the number that changed +Qy into -6:

2x - 6y = 8

2x + Qy = 8

The 2x's cancel out, and then remove the equals and the 8:

-6y = Qy

<h3>So Q must be -6</h3>
