J-Hope loves pizza --- he eats it for lunch every day. His two favourite pizzas restaurants are Do chef Nonhyeon ("Pizza A") and Giannis Nappoli ("Pizza B"). His fans would like to predict which restaurant he'll go to in order increase the chances that they "just happen" to be there when he comes by. Being keen linear algebra students, they know just what to do... First, they assume that his restaurant choice could depend on where he went the day before, but not on any days prior to that. (J-Hope has a short memory.) They then collect data on his patterns. They observe that out of 315 times that he ate at Pizza A, he returned to Pizza A the next day 150 times. The other 165 times that he ate at Pizza A, he went to Pizza B the next day. They also observe that out of 248 times that he ate at Pizza B, he went to Pizza A the next day 64 times. The other 184 times, he returned to Pizza B the next day
