Answer 1

Answer:

Both the people can have separate rooms and the other can be a spare room. Or both people can stay in one room and the other two rooms can be a kitchen and dining room.

Answer 2

Answer:

There are 3 ways in which they can accommodate the room

Step-by-step explanation:

Number of people = 2

Number of rooms = 3

We are supposed to find the no of ways in which they can accommodate the room

So, We will use combination :

Formula : $^nC_r=\frac{n!}{r!(n-r)!}$

The no of ways in which they can accommodate the room =$^3C_2$  

                                                                                                 =$\frac{3!}{2!(3-2)!}$

                                                                                                 =$3$

Hence there are 3 ways in which they can accommodate the room
