Lol - well, yes, this is an easy question. It won't make you look dumb though, because it's just a drawing convention. All of the bonds in this molecule (methanol, incidentally) are single bonds.
The problem is that molecules exist in three dimensions and the only way we can draw them is in two dimensions. Consequently, when you need to show three dimensional structure, you have to find a two dimensional way to do it. One convention is to use a wedge-shaped solid bond to show that the bond is coming out of the paper, and a wedge-shaped dashed bond to show that the bond is going back into the paper. Straight lines are used for bonds in the plane of the paper or for bonds whose 3-D structure isn't considered significant.
Carbon with four single bonds exists in a tetrahedral conformation, with the four bonds pointing out to the corners of the tetrahedron. So if you imagine the C atom at the center of a tetrahedron, with the O at one corner and the hydrogen at the bottom at one corner, you can see how the other two hydrogens would be arranged at the other two corners.
