27.A and B are highly truthful (they each tell the truth randomly 3/4 of
the time. Also, A's and B's truthfulness are independent. Suppose A and B both look out the window to see what the weather is like. A says, "It's raining." B says, "It's raining." What is the probability that it actually is raining.
my comment : do we need the probability of raining.

chance of person A lying 1/4
chance of person B lying 1/4
Multiply to find chance of both lying:1/16
15/16, therefore, is the chance of both telling the truth.
