You are visiting a small town in a foreign country with 3 major cell phone carriers, namely A, B and C. It is known that when a tourist dials a number on his/her phone, it will randomly connects to one of these carriers with 40%, 25% and 35% of the time, respectively. It is also known that 90% of the calls through carrier A, 95% of the calls through carrier B and 80% of the calls through carrier C are successful in general. If you make a successful call on your phone, what is the probability that the call goes through carrier A? (Use Baye's Theorem)
