This is just the probability of both of them are accurate. Does not mean this is same as probability of answer being Yes.

Then in order to use Baye's theorems for conditional probabilities,
 we need to know the REAL, actual probabilities that the answers are yes or no.
 
Ex. P( answer is Yes |  A is correct)
 
We are not given such probabilities.
