    Say, there exists 2 humans and 98 bacteria. Consider all cells of a human one life.

    50% of ALL life doesn’t care which species the life is, and therefore there’s a chance that 50 bacteria die. The probability of that happening is 98C50 / 100C50 = 98! 50! 50! / (100! 50! 48!) = (50)(49) / ((100)(99)) = 0.247

    For my previous argument, I did not actually do the math. Now that I have done a little bit, the probability seems to converge at 25%

    Obviously, this is based on the interpretation of “all life”. For my interpretation, “all life” includes every life in a single set, and apply the 50% snap to that. For some others however, it may be interpreted as each species in their own set, and the 50% snap is applied on all those sets.

      But if there are 7 billion humans and n bacteria, and 50% of them are snapped, wouldn’t approximately 3.5 billion humans and n/2 bacteria be snapped?
