And that means there are three orbitals. Now, these guys are the p orbitals. Remember, there are three P orbitals. There's one in the X direction. So if we draw our XYZ axis, our three dimensional axis, that means our P orbital is in the X direction, our PY orbital is in the Y direction, and our PD orbital is in the Z direction. In other words, if we put all these guys together, we get three orbitals.
