Photo and Video Sharing. Photos and videos have become an important part of the online social experience, with more than half of

Internet users posting photos or videos online that they have taken themselves. Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves. Pew Research Center finds that P(A)=0.52,P(b)=0.26,, and P(AorB)=0.54. What is the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves? (Round your answer to three decimal places.)

Answer: 0.923

Step-by-step explanation:

Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves.

Pew Research Center finds that

P(A)=0.52    P(b)=0.26,  and P(A or B)=0.54.

To find : P(A|B)

Since , \text{P(A or B)=P(A+P(B)-P(A and B)}

i.e. \text{P(A and B)=P(A)+P(B)-P(A or B)}

\text{P(A and B)=}0.52+0.26-0.54=0.24

Now, using conditional probability formula ,

P(A|B)=\dfrac{\text{P(A and B)}}{\text{P(B)}}\\\\=\dfrac{0.24}{0.26}=0.923076923077\approx0.923

Hence, the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves = 0.923

In this diagram which equation could you prove to be true in order to conclude that the lines are parallel
KiRa [710]
I would say that the correct answer is D. because y is always the numerator while x is the denominator for the equation y2 - y1/x2 - x1 which means if there is two y's or two x's on the same line you subtract the second one from the first one. If there is only one y and/or x and the other is 0 on the same line, it stays at y or x without subtracting y2 - y1 or x2 - x1. 

Since b is on the y coordinate and -a is on the x coordinate, you would make it b/a while -a is gonna be a positive since the lines are going up and to the right. Now, since c is the y coordinate and d is the x coordinate, make C the numerator and d the denominator since y is always the numerator and x is the denominator for these parallel line figures on the graph and the equation will be equaled to the fraction to the other fraction for parallel lines. 

So, your answer would be D. b/a = c/d 

Hope this helps, and is correct!
