Gareth's prediction would be wrong because there is a equal probability of the coin landing heads up every single time, or landing tails up every single time

well - there is an equal chance of h/t each throw that means that there is just a chance that (for instance) he will throw 820 heads (this is an infinitesimally small chance - but it still exists) The distribution of probability is bigger as you get to 420 heads, but ANY combination of 820 heads or tails has a finite possibility, therefore he cannot be confident that exactly 410 heads will occur

I have just looked up the probability it is only about 2.8% chance that exactly 410 heads will be thrown !!
