Complete question:
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)= 0.6 and P(B) =0.05. What is P(B|A)?
Answer:
P(B|A)= 1/12 ≈ 0.083.
Step-by-step explanation:
Since B is contained in A, then A∩ B = B and
P(A|B) =
P(A ∩ B)/P(A)
P(B)/P(A)
=0.05/0.6
= 1/12 ≈ 0.083.
