Hello!
.
The answer to your question is 495 ways.
.
n = 12
r = 4
.
nCr = n1 / (n-r)! r1
12C4 = 12! / (12-4)! 4!
12C4 = 12x11x10x9x8! / 8! 4!
12C4 = 11880 / 24
12C4 = 495

Answer:
48%
Step-by-step explanation:
We have 3 people and 5 floors
We can't have two or more people leaving in the same floor.
So, the first person to leave has 5 possibilities (all 5 floors)
Then, the second person will have only 4 possibilities, as this person can't leave in the same floor as the first one.
Lastly, the third person will have only 3 options (the 3 remaining floors that weren't selected).
The total number of possible choices, without restrictions, is 5 possibilities for each person, so 5*5*5 = 125 combinations
The combinations we want is 5*4*3 = 60 combinations
So the probability of all people choosing different floors is 60/125 = 0.48 = 48%
