One bag contains 11 red balls and 3 green balls. A second bag contains 7 red balls and 9 green balls. Bob reaches in and selects one ball from the first bag and places it in the second bag. Then Alice selects one ball from the second bag. If Alice's ball is green, what is the probability Bob had selected a green ball?

A board is made up of 16 squares. Each square can only fit one coin. The four squares in the center of the board are gray and the rest is white. Malcolm randomly tosses a coin blindfolded. Without removing the first coin, he tosses another coin.
