Rowan is a musician. His music is hosted on two separate music streaming services, A and S. The number of times Rowan's music is listened to per day on service A follows a Poisson distribution with mean 105. On service S, it follows a Poisson distribution with mean 250, independently of service A. Let T be the total number of times Rowan's music is listened to per day across both streaming services. a State the distribution of T. b Find the probability that Rowan's music will be listened to more than 400 times in a day.
