As written, this is a strange question! You imply that you
do not have data on the response (0/1) variable at all,
only on the explanatory variables. In that case there is
no possible estimate, because that would require data on
at least some of the values of the response variable.

I think you should explain more clearly and explicitly what
the information is that you have for all the variables.
