Difference between 'likelihood', 'possibility' and 'probability'?

Is there any difference of the magnitudes represented by these words? I often hear people saying 'It's possible, but not probable' or things alike. Can someone explain? Thank you very much!:-?

It's possible- not very likely >50%
It's likely/probable <70%

These percentages are just to give an idea.

It's likely to rain- take an umbrella
It's possible that it will rain- take a gamble and leave the umbrella.
;-)

I would also like to know if we can use 'possibility' in expressions like "there is evey possibility that she is given a job" or we must say "every likelihood" instead. Is it a collocation?

Thank you.

Here are some examples of there is evey possibility that:

There is every possibility that this war will lead to greater incidents of terrorism and greater possibility for the proliferation of weapons of mass destruction.

BBC NEWS | Technology | Home PCs hijacked to spread spam
Even if you use anti-virus software but do not keep it up to date, there is every possibility that you are helping to keep spam alive and spreading.

BBC SPORT | CRICKET | Calling time on chucking
Quite simply, there is every possibility that no bowler will ever be called for chucking again in a Test match.

And while there are "no plans" for Obama to appear in the convention hall tonight, there is every possibility that he will make a surprise appearance onstage.

I hope this helps.

Yes, you can use 'possibility' here, but in either case you'd have to say:
"There is every possibility that she will be given a job".
