A certain shop repairs both audio and video components. Let A denote the event that the next component brought in for repair is an audio component, and let B be the event that the next component is a compact disc player (so the event B is contained in A). Suppose that P(A) = .6 and P(B) = .5. What is P(B|A)?

Step-by-step explanation:

Given Events :

A =  Next component brought in for repair is an audio component.

B= Next component is a compact disc player.

Also, P(A)=0.6   and P(B)=0.5

Since B is contained in A.

So, A∩B = B

Then, P(A∩B)=P(B) = 0.5

Conditional probability formula :

Substitute values , we get

Hence,

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
