Tire help! Are the tires on the Cannondale Quick 2 wide enough for gravel?

I’m probably going to buy the Cannondale quick 2 for women.... but I’m concerned that the tires are too narrow.   I want a quick bike with no shocks that can do mostly pavement but also some light dirt and gravel.    Will this bike work... can I buy wider tires with it to help... which tires are even compatible?
