1*(3/4)*(2/4)*(1/4) = 6/64 = 3/32

The first person can pick any number (probability of 1).
The second person can pick any of the 3 remaining numbers (probability of 3/4).
The third can pick any of the remaining 2 (probability of 2/4 or 1/2).
The last can pick 1 of the 4 numbers (probability of 1/4).

Multiply each of these together to get the total probability (likelihood) = 3/32
