What are the chances of one engine going out in a 747 during
flight?

Depends

I'm not talking about an engine falling off the jet, but just stop
working. Also, what are the chances of two, three, and four engines
going out? What about the two jet engines on a 777?

?Just wondering
what the odds were.

Thanks!

Did you know a 747 can carry five engines. There's an extra inner pylon
mount on the port wing for ferrying engines.

FWIW, in the past, I worked on a C-135 that had provisions for 6
engines. The two extras, were for generating extra electrical power.

Prove it.

So, I now I wonder why just the port wing? If you are going to have an
extra pylon on one wing, why not both?

Getting back to the original question...

Twin-engine turbine powered commercial aeroplanes have an "in-flight
propulsion system shutdown rate" of approx 0.02 per 1000 hours.
(Source: ICAO ETOPS approval papers)

You will have to work the rest out. That's all I can help you with.

not a lot of call for transporting two engines to a stricken machine. And
if you did need even a whole set, all you'd have to do is cycle them out
there one at a time on your scheduled service.

Flounder,
Tell me if you looked twice when you saw the 5 engine version. I sure
did.

To some others posting:
I am told be a friend that is an airline wrench that all 747 have the
transport keystone (thing the pylon mounts to) plate in one wing
typically port - some were special ordered with it starboard, but he
saw no indication for both sides.

The extra engine has to be fitted with fairingson the ends and has not
provision to be fueled.

Those things are much too big to actually fly.

and they'r enot nearly the biggest thing flying. I saw the Ant224 a few
years ago ('88 I think) in Paris and it just took up the whole sky from
where I stood.
