The 40-year-old has replaced Ole Gunnar Solskjaer on a temporary basis until an interim manager is appointed for the remainder of the season.
He takes charge of his first game as Man United's caretaker boss in a crucial Champions League fixture against Villarreal tonight.
But a supercomputer doesn't like his side's odds against the La Liga outfit as they have been given a 42 per cent chance of winning in Spain, according to results via The Sun.
And United have just a 17 per cent chance of beating league leaders Chelsea on Sunday, with the club having a 48 per chance of coming out on top at home to Arsenal on December 2.
However, Man United's chances of winning increase and they could put together a little winning streak in home matches against Crystal Palace and Young Boys.
The Red Devils have a 58 per cent chance of securing three points at Norwich and have a 56 per cent chance of beating Brentford.
But their chances of winning decrease when they host Brighton on December 18, with a 49 per cent of earning a big win.
The Old Trafford club, though, have been backed to beat Newcastle United and Burnley.
Carrick spoke to the press on Monday ahead of taking charge of his first game against Villarreal.
He said: "Obviously I've worked closely with Ole for a long time now and we do have very similar beliefs. We did as players and we certainly do as coaches and manager.
"Of course, I've got my own personality, but it's very similar, that's why we worked together for so long and it went so well for a period of time.
"I'm not giving too much away of what my plans are but I'm very clear in my own mind what we want to do. I have my own ideas about how we want to play, how we want to go about it and I'm looking forward to seeing that on the pitch."
