If you have a brand new set, and a few parts are missing, you should definitely contact LEGO Customer Service, so they can send you the parts you are missing.
New sets with missing parts
We’re really sorry to hear that something was missing from your new LEGO® set. We do our best to make every set perfect and we take it very seriously when a faulty one sneaks through. Don’t worry though, we can send you the parts you need!
Please click “Missing Bricks” on the Bricks & Pieces section of our Customer Service site to order the part you need to finish your set.
If you can’t find what you’re looking for, make sure you include a complete description of the part (the part number provided in the inventory page at the back of the building instructions is useful) along with the set number. Once your part is on its way, we’ll send you a shipping confirmation email.
If you’ve lost some bricks over time, please remember to click “Buy Bricks” instead.
Just tell them the part numbers you are missing and they should send you the parts for free.
You can purchase them both at Bricklink.com.

Could it be that there're parts missing in a LEGO box?
Yes, it is possible that pieces do end up missing from the time a set leaves the LEGO factory to the time the box ends up in our hands.
Without further information we don't know the exact reasons why this happens without proper polling, collecting, and disseminating these results.
We could speculate the reasons through past experiences. In the past I had recently finished watching the movie Gremlins and was sure one of those things got into my box and took a piece, but in reality that piece was stuck in the inner crevasse of the box.
So, for me: User error or self-Trolling was the culprit.
Or at any rate, you can follow what Alexander O'Mara has suggested, and contact LEGO Customer Service to get your parts replaced for free.
Could it be that there're parts missing in a LEGO box?
Rin Rio-Oki has pointed you to the place where you can definitely get replacement parts, but to answer your first question, yes, it is indeed possible, though the chances for it are negligible. In any case, you should let LEGO know about it via their official support channels (even if you are planning to get the replacement parts from Bricklink), so that they are aware of the problem and can take steps to mitigate such accidents in the future.
