It's actually quite hard to solve using only elementary geometry. If you're lost, try using trig first to get the answer, and then come back and try using just elementary geometry.

Let the length of AB be 1. Then use the Law of Sines and/or the Law of Cosines to find the length of AD, and other relevent lengths and angles. Refer to the figure in >>389233. (Note that this is somewhat cheating because it uses trig, but figuring out how to solve it with just elementary geometry is really fucking hard.

If you flip two coins, there are four equally likely possibilities:
P(HH) = 1/4
P(HT) = 1/4
P(TH) = 1/4
P(TT) = 1/4

"At least on heads" means HH, HT, or TH.
So P("Both are heads" given "At least one is heads") = P(HH) / (P(HH) + P(HT) + P(TH)) = 1/3

Gottem!

I'm reasonably certain HT and TH shouldn't be considered unique instances in the context of this problem, but whatever.

 No.389375

>>389374
Even though you have eliminated the possibility of two tails, the probability of a heads/tails mix is still double the probability of heads/heads. It's a completely different problem than saying given the first coin is heads rather than at least one of the two is certainly heads.
