Search and Rescue (S&R) is looking for an entity that has been reported lost. The entity is either in town A (with probability 0.4) or town B (with probability 0.6). On any given day, if the entity is in A and S&R spends a day searching for it in A, the conditional probability that they will find the entity that day is 0.25. Similarly, if the entity is in B and S&R spends a day looking for it there, the conditional probability that they will find the entity that day is 0.15. The entity cannot go from one town to the other. c) If S&R flips a biased coin (probability A = 0.3) to determine whether to look on the first day and finds the entity on the first day, what is the probability that they looked in A?
