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?

Question

Well for one, she's got probability wrong. But first:
Is this a free-response question?

yes

Okay. Sorry I'm responding to 2 math questions right now.
Basically, when you flip a coin EACH TIME is fifty-fifty (or half-half) chance of getting heads or tails. Not "half of your flips will be heads/tails" the statistical logic is incorrectly applied here

ok thanks

kittybasil · Answer

I guess you could shorten that to "each flip has a 50-50 chance of being heads or tails, not the whole sum of your flips" if that makes any sense.

(Sorry still trying to answer the other Q)
