Hi! How are you? I had the same thought process of placing the two bedrooms as one sample space. However, I interpreted the question as finding number of ways for the bedrooms to have identical colours and having repeated colours for the other 5 rooms (excluding the colour chosen for the 2 bedrooms). With which, I came up with 9 X (8^5). 9 being sample space of 2 bedrooms and (8^5) being sample space of the other 5 rooms with repeated variations. My question is, if that is a possible way to calculate the number of ways? Thank you for your time!

Hey Ruijie, Thank you for reaching out! The question is open to interpretation and I think your way of solving the task is completely valid :) Kind regards, 365 Hristina
