Evelyn believes that if she flips a coin 480 times, it will land tails up exactly 240 times. what would you tell evelyn about her prediction?

You'd say that although that seems correct, since there's a 50/50 chance of each outcome, it doesn't necessarily guarantee that it will ALWAYS be 50/50. However, her guess has the highest probability of occurring, or in other words, its more likely that it'll be somewhere close to 240 rather than in the 100's or 300's.
