Let's say we have a truth table (AND) like this:

F F = F
T F = F
F T = F
T T = T

Where A and B are 2 coins that randomly can be True or False (the two faces). So now I throw the two coins, what is the probability to get True on both?

During an interview I just said 1/4 but they said that it's wrong, it is 3/4 and right now I'm lost.

Can you please help me? Thanks

Unless you have misremembered the problem or something like that, you are right and they are wrong. 3/4 would be right for OR.
