inp is of type ('a *float) list, so the inp.Map line has to be changed to
(List.map (fun (x,v) -> (x,(float v/float total))) inp)
The warning can be eliminated via replacing List.sumByInt with
List.sum_by (fun (_,v) -> v)
(Haven't tried it out, but should be correct as far as I see)
The warning is the not problem; error is the problem.

I have a problem with Expert F#, at bottom of the page 241.
let countedCases inp =
let total = List.sumByInt (fun (_,v) -> v) inp // WARNING
weightedCases (inp.Map

Error 1 The field, constructor or member 'Map' is not defined.
Warning 3 This construct is deprecated. This function has been replaced by 'List.sum_by'
