Answer:
Step-by-step explanation:
Given that ![P[A_1]=0.1,\\P[A_2]=0.3,\\P[A_3]=0.6](https://tex.z-dn.net/?f=P%5BA_1%5D%3D0.1%2C%5C%5CP%5BA_2%5D%3D0.3%2C%5C%5CP%5BA_3%5D%3D0.6)
Since total gives 1, we find that these three events are mutually exclusive and exhaustive.
E is one event such that
![P[E|A_1]=0.3\\P[E|A_2]=0.6,\\and P[E|A_3]=0.3](https://tex.z-dn.net/?f=P%5BE%7CA_1%5D%3D0.3%5C%5CP%5BE%7CA_2%5D%3D0.6%2C%5C%5Cand%20P%5BE%7CA_3%5D%3D0.3)
![P(A1E) = P(E/A1)*P(A1) = 0.03\\P(A2E) = 0.18\\P(A3E) = 0.18\\P(E) = sum of these 3 = 0.39](https://tex.z-dn.net/?f=P%28A1E%29%20%3D%20P%28E%2FA1%29%2AP%28A1%29%20%3D%200.03%5C%5CP%28A2E%29%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3D%200.18%5C%5CP%28A3E%29%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3D%200.18%5C%5CP%28E%29%20%3D%20sum%20of%20these%203%20%3D%200.39)
![P(A1/E) = P(A1E)/P(E) = \frac{0.03}{0.39} =0.0769\\P(A2/E) =\frac{0.18}{0.39} =0.4615\\P(A3/E)= 0.4615](https://tex.z-dn.net/?f=P%28A1%2FE%29%20%3D%20P%28A1E%29%2FP%28E%29%20%3D%20%5Cfrac%7B0.03%7D%7B0.39%7D%20%3D0.0769%5C%5CP%28A2%2FE%29%20%3D%5Cfrac%7B0.18%7D%7B0.39%7D%20%3D0.4615%5C%5CP%28A3%2FE%29%3D%200.4615)
