When Ted is looking for his pen, the probability that it is in his pencil case is 0.7. If his pen is in his pencil case he always finds it. If his pen is somewhere else, the probability that he finds it is 0.2.

Given that Ted finds his pen when he is looking for it, find the probability that it was in his pencil case.
