To elaborate on Kushan04's post, in the game settings there is a series of checkboxes giving you options on what to display in your message log. The box you want to check is called "Weapon Endgame Calculations" or something like that (I don't have the game in front of me).
If you check that box, your message log will display the calculations used for each weapon or shot fired. Base hit %, any modifiers, results of countermeasures, etc., and then the final base chance to hit. And, of course, the final die roll!
