How do i make someone brainliest? (if you answer me, i might be able to make you brainliest! )

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?

Solve the equation.then check your solution 8=1.88+a
