If you tossed two coins simultaneously 400 times, would you expect the standard deviation to be greater or less than it was 40 times?(adsbygoogle = window.adsbygoogle || []).push({});

I think tossing 2 coins 400 times would give a greater standard deviation because the sample size is larger so the standard deviations can be quite far from the mean?

Im not sure if that makes sense PLZ HELP! Im not good at probability.
