please help me with this small problem

Write a predicate min with the following property: min(A,B) succeeds
iff A is a list of numbers and B is the minimum value in the list. E.g.,
min([4,1,5,9,3],X) should succeed with X = 1.

What did you try ?
You should read other threads on this forum, you would find the solution.

for simple atomic statement

max(X,Y,X):-X >= Y.
max(X,Y,Y):-X < Y.

And for one list of numbers.

maxLis( [] ).
maxList( [E],E ).
maxList( [E,E2 | T],L ):-maxList( [E2 | T],L1 ),max(L1,E,L).
