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,

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
