Pls answer will mark brainliest! Ashlyn is having new hardwood flooring installed at the living room kitchen and dining room if the flooring cost $4.25 per square foot, how much will she spend? ​

There are three bags: a (contains 2 white and 4 red balls), b (8 white, 4 red) and c (1 white 3 red). you select one ball at random from each bag, observe that exactly two are white, but forget which ball came from which bag. what is the probability that you selected a white ball from bag a?
