Do the odds reflect the probability? I thought that everytime a coin was flipped it was a 50-50 chance. Therefore it shouldn't matter which order the coin toss was won in?

Prob(at least 1 tail) = 1 - prob(no tails) = 1 - prob(all 5 heads) = 1 - 2^5 = 31/32.

Probability = Asking the drunk slag at the bar for a root
