In one of the questions related to coin tosses, the answer option provided is incorrect. From what I know, of exponent rules, `a^n * a^n = a^{2n} and not a^{2^{n^2}}.

What is shown in the screenshot above should actually read as n^2_{C_n}/2^{2n}

Hi @sundeep,

Yes, the answer is incorrect. Thanks for pointing, but note that it will still not be the one you suggested. As both the exponents are not the same.

Sure. You are correct

\frac{1}{2}^n * \frac{1}{2}^{(n^{2}-n)} = \frac{1}{2}^{n^2}
