Just tried the coin toss prompt and get the following
Your strategy should be to always call "heads," since it has a higher probability of landing on heads (52%) compared to tails (48%). By consistently choosing heads, you'll earn more money in the long run.
And to prove taht the square root of 2 is irrational:
The proof that the square root of 2 is irrational is a well-known proof that uses contradiction. Here's one way it can be shown:
Suppose, for the sake of contradiction, that the square root of 2 is rational, meaning that it can be expressed as a fraction of two integers, a/b (where b≠0). Then, we can square both sides of the equation a/b = √2, which gives us:
a^2/b^2 = 2
Since a/b is in its lowest form (the numerator and denominator have no common factors other than 1), it follows that a^2 and b^2 have no common factors other than 1. But then, 2 must also be a perfect square, which it is not. Therefore, our assumption that the square root of 2 is rational leads to a contradiction, and we must conclude that it is indeed an irrational number.
