Answer 1

Answer:

Thus, the number of ways the7 students can be assigned to 1 triple and 2 double hotel rooms during a conference is 210.

Answer 2

Answer:

1260 ways

The triple room will be occupied by the first 3 people, so no. of ways = 7C3

The first double room will be given 2 people thus no. of ways is 4C2

So, total no. of ways is 7C3x4C2x2C2 = 1260 ways
