He has not been mention or announce dead
Even Piell lost his eye as a cost of him foiling an assassination attempt on a royal member of his species on his homeworld.
You may be thinking about Jedi Master Even Piell a Lannik, which is not the same species as Yoda; but Piell did not appear in "Revenge of the Sith". He did appear in Episode I and Episode II, but died during the Clone Wars.
No. He is dead cause remember how badly charred his helmet was? And if you have a sharp eye like I do, Echo's helmet was the only thing that was left after that explosion (the ship doesn't count in this case)
Probability of rolling an even number on a die is 1/2.
Aayla Secura, Barriss Offee, Adi Gallia and Aurra Sing have already appeared in the series. Shaak Ti will appear in Season 3 that will begin in the fall of 2010. But as for Stass Allie, Valorum, Even Piell, Oppo Rancisis, and Durge: I don't think so.

There are countless Jedi. But some most famous ones are Anakin Skywalker, Obi-Wan Kenobi, Yoda, Ahsoka Tano, Mace Windu, Luke Skywalker, Plo Koon, Galen Marek a.k.a "Starkiller," Kit Fisto, Ki-Adi-Mundi, Aayla Secura, Shaak Ti and Even Piell
There are 6 numbers on the die; 3 even. Therefore P(Even) = 3/6 or 1/2.
