Gareth believes that if he flips a coin 820 times, it will land heads up exactly 410 times. What would you tell Gareth about his prediction?

I would tell Gareth that he is wrong, and right.

Step-by-step explanation:

When dealing with a coin flip, there will be a 50/50 chance for it to land heads or tails every time, but this doesn't mean that it will land like that every time either. It could land 819 times heads and 1 times tails, but unless something is affecting it each time the probability won't change.
