Question

welshfella · Answer

can we assume that they all start from the ground floor?

mani2596 · Answer

yes

welshfella · Answer

so one person can go to any one of 14 floors.
probability he gets out at floor 1 = 1/14
probability that the other 2 get out at this floor also = 1/14 * 1/14 * 1/14

Statistics is not my strong point so i would advise another opinion

welshfella · Answer

the other possiblities are  they all get out at floors 2 to 14.
So the required probability = 14 ( 1/14 * 1/14* 1/14) =  14  */ 2744 = 1 / 196
