Yes and No. White dwarfs generally form from stars that have too low a mass to become supernovae. However, if the white dwarf has a companion star, it is possible for the white dwarf to accrete additional fuel from the neighboring star and then it can explode as a nova {See Link} or a Supernova type La [See link]
A Type Ia supernova is created by the merger of two white dwarfs. This type of supernova occurs when the combined mass of the white dwarfs exceeds a critical limit, leading to a thermonuclear explosion that destroys the star.
According to prevailing astronomical theory, red dwarfs do not become supernovae, so the best answer to the question is "nonexistant."
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into a white dwarf.
Actually if a star is medium or low mass is will run out of fuel and turn into a red giant, once the stars atmosphere slowly drifts away and the core is remaining it will eventually become a white dwarf For more massive stars it will turn in to a super giant the will cause a supernova, after the supernova the star can either a black hole or a neutron star

No. Stars become white dwarfs after dying.
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.

No. Intermediate mass stars will evolve into Red Giants and then to White Dwarfs. See related questions for more information.
Percentage wise. Most stars do not explode. Only about 1 in 3 million will explode as a supernova. The rest, like our Sun will just die quietly and become white dwarfs.

Stars that have ejected a planetary nebula eventually become white dwarfs. These are core remnants of low to medium mass stars that have exhausted their nuclear fuel. White dwarfs gradually cool down over billions of years to become black dwarfs.
Supernova. Stars below nine solar masses become white dwarfs, though stars more than 1.4 solar masses (Chandrasekhar limit) should nova during their life time. http://en.wikipedia.org/wiki/Supernova http://en.wikipedia.org/wiki/Chandrasekhar_limit
Red dwarfs have not yet evolved into white dwarfs because red dwarfs are much less massive than other types of stars that do become white dwarfs. Red dwarfs are the smallest and coolest stars, and they have not burned through their fuel quickly enough to go through the stage of becoming a white dwarf. It will take billions of years for a red dwarf to cool and fade into a white dwarf.
