Can I play a 6gb ram game with a 4gb ram pc?

I planned to buy assassin's creed unity, and when I checked the minimum requirement of the specs of the game it need 6gb ram, but I only have 4gb ram. Can I play it smoothly?
My pc is Lenovo laptop windows 8.0,
Intel Core i5-3230M CPU @ 2.60GHz,
4gb ram with 3.86gb usable
64-bit operating system, x64-based processor
Nvidia GeForce GT 740M version 311.27
no game card

I can play games like black ops2 and battlefield 3 just sometimes will have some glitch. So I wonder if Assassin's Creed can work on my pc.

Not but not really because of your ram but what is really important in a PC game is your PROCESSOR, your graphic card is ok but your CPU should be 3.3 GHz or higher to get full speed

What part of "minimum requirements" don't you understand?

No. 4<6. Do they not teach simple arithmetic in schools anymore?
