Answer:
In AM, the carrier wave's instantaneous voltage is varied by modulating waves voltage. On transmission, noise signals can also be added and receiver assumes noise a part of the modulating signal. However in FM, the carriers' frequency is changed as per modulating waves instantaneous voltage. This can be done at the mixing / modulating stage and not while signal is transmitting in channel. Hence, noise doesn't affect FM signal.
