Binomial trial. Prob (h) = .5 × .5 = .25. The first part of the question is a red herring.
How smart is Any Forums?
Just multiply probability of each event together since they're independent
p = (1/2)*(1/2) = 1/4
retard alert
you must be mexican then
It's not a red herring because one coin is guaranteed to land heads.

>ONE coin landed heads.
you don't know which coin has landed heads
Retards, at least one coin landed heads. Conditional probability. It cannot be 1/4 given the condition that at least 1 coin landed heads. Tails-Tails is no longer possible.
It's 1/3
''one of them landed heads''
therefore take out a coin. put one of them on heads. do not move it, spin it, or shove it up your ass.
now infinitely flip the other coin, 2 outcomes, equal chance.
it's 50/50.
