What is the probability that there are more heads than tails if a coin is flipped n times?

**A says) Silly question! It is obviously 1 / 2.**

**B says) Nope.**

**C says) I have to agree with B. A's answer is wrong half the time!**

**D says) A again! He is the man!**

**E says) As usual A's answer is gibberish. Next to A, B looks like a genius.**

**What do you think?**

Hi gAr;

I will need to look at that then. Would you say that was a difficult problem?

Hi bobbym,

Okay.

I think it was a relatively easier one.

I tabulated the values for a few small n's and figured it out...

Hi bobbym,

I'm fine. Formal education is wasting my time. I'm forced to do things which I despise!

How are you doing?

Hi gAr;

Bothered by a migraine, other than that okay. I think I am going to just close my eyes and rest for a while. See you later.

Hi bobbym,

That must be uncomfortable.

You sleep well instead of just closing the eyes.

See you later.

Hi gAr;

That is exactly what happened. Went out like a dead lightbulb.

Okay, what courses are they making you take?

Hi bobbym,

Glad to hear that it's gone.

More than the courses, it's those people around, arrogant and jerks!

Teachers! Not all of them, though.

Also ignorant, I may add.

I think there'll be such people anywhere I go! But I do not know how to deal with it.
