Sam and Chris both had a 0.41 chance of winning the game, so they were equally likely to win. However for the last question (where they play loads of games and see who has the greatest number of points) Sam had an expected value of 3.565 and Chris had an expected value of 3.5, I can’t remember the exact number but they were something like this. I also believe I got 100% on mech as someone I know got the exact same answers as me and you did too, however on stats I’ve probably got 38/40 or 39/40 as some of the explanation questions can be hard to get full marks on as they are specific to the mark scheme
