New address which is already in use?

What is the probability to generate a new address which is already in use?

very very very very very low

Sometimes however you will get a wallet with a bad RNG (e.g. blockchain.info android wallet) which generates the same address for different people, but those cases are very unlikely to happen.

What is the probability to generate a new address which is already in use?

It is expected to be approximately

1 in 1.4615x10⁴⁸

That's 1,461,500,000,000,000,000,000,000,000,000,000,000,000,000,000,000

For a reference to get a feel for just how big that number actually is, consider that it is estimated that the diameter of the observable universe is about 8.8×10²⁶ metres or 5.5×10²³ miles.

That's 880,000,000,000,000,000,000,000,000 metres
or 550,000,000,000,000,000,000,000 miles

The Universe is constantly expanding and accelerating, pulling our observable universe further apart. So the diameter of the observable universe is increasing all the time.
