Is it possible to draw a round?

If the last survivors of both team die at the same time (by a grenade, for example), who wins? Is it possible to get a draw? If yes, does the round still count in the 30 rounds of competitive?

@CommandoAir's Answer was correct, it is not possible, one player always dies first, even if the time diffrence is only milliseconds. It was possible in previous CS version due to grenades, but its not possible in CS:GO.

Here is the video from 3kliksphilip:

No it's not possible.

One further example is a sniper duel. When you get hit first, even if you hear your shot, it will not take effect, the shot "magically" disappears.

One person always dies first!
